Chemiresistive effect of p-type delafossite CuScO2 microsheets to gaseous alcohols.

The chemiresistive effect of an oxide significantly influences its electrical properties, which depend greatly on the interactions between the ambient gas molecules and the solid surface, including the gas adsorption and charge transfer still challenging to be clarified. In this work, we investigate the chemiresistive effect of the p-type delafossite CuScO2 microsheets by comparing their responses to various gaseous alcohols, which increase with an approximately linear relationship with the length of straight carbon chains from methanol to n-hexanol. A new mechanism is proposed to elucidate such a dramatic trend of observed chemiresistive change based on the first-principles calculations and test results. The increasing carbon chain length modulates the adsorption configuration and provides supplementary routes for electron transfer, which is assumed to account for the observed chemiresistive effect. This work may provide a novel perspective for the investigation and development of more advanced functional oxides for electrical applications.

Spin-resolved transport of multifunctional C18 molecule-based nanodevices: a first-principles study

As is well known, Kasier et al first synthesized a cyclic molecule C18, as characterized by high-resolution atomic force microscopy, is a polyalkylene structure in which the 18 carbon atoms are linked by alternating single and triple bonds Kaiser et al (2019 Science 365 1299–301). Early studies have found that the C18 molecule has semiconducting properties, suggesting that a similar straight-chain carbon structure could become a molecular device. Inspired by this, an analysis of spin-resolved electronic transport of nanodevices made by C18 sandwiched between zigzag graphyne nanoribbon leads or zigzag graphene nanoribbon leads presents here. The computational results demonstrate that a good spin-filtering effect, spin rectifying effect and an obvious negative differential resistance behavior in designed model devices can be obtained. Moreover, a stable dual-spin filtering effect or diode effect can be occurred in considered model devices with leads in an antiparallel state. The intrinsic mechanisms of molecular nanodevices are explained in detail by analyzing the transmission spectrum under different bias voltage, local density of states, molecular projection Hamiltonian, Current–Voltage (I–V) characteristics, transmission pathways, et al. These results are particularly significant for the development of multifunctional spintronic nanodevices.

Synthesis of ultra-thin 2D MnO2 nanosheets rich in oxygen vacancy defects and the catalytic oxidation of n-heptane

N-heptane (C7H16) is a kind of VOCs from a wide range of sources, which harm to the atmosphere and human health. So far, most of the researches on C7H16 have focused on catalytic cracking rather than its low temperature degradation. As a kind of long straight carbon chain alkanes, the study of catalytic oxidation of C7H16 has a certain guiding value for the degradation and mechanism analysis of complex organic compounds. In our study, 2D birnessite-MnO2 nanosheet with the thickness of 1.7–2.5 nm was successfully prepared and it can achieve complete conversion of C7H16 at 252.31 °C, which is better than the bulk catalyst. The characterization (such as TEM, XRD, etc.) and kinetic experiments results showed that it has good catalytic oxidation performance due to its ultra-thin, large specific surface, abundant oxygen vacancies and excellent electron transfer efficiency, which not only exposes more surface atoms, but also absorbs more gaseous O2 and rapidly transforms into reactive oxygen species (ROS) that can participate in catalytic oxidation. Surface reactive oxygen species play an important role in catalytic oxidation due to the formation of surface oxygen vacancies.

Study of the Co-pyrolysis characteristics of oil shale with wheat straw based on the hierarchical collection

To reveal the co-pyrolysis characteristics of oil shale mixing with wheat straw in different reaction steps, three temperature stages of 348 °C-T1, 476 °C-T2 and 521°C-T3, which were obtained through the thermogravimetric analysis results, were chosen as the collection temperature of the liquid products. The volatiles of each temperature stage would be condensed and collected separately and successively for the depiction of the detailed co-pyrolysis characteristics. Through the comprehensive analysis of the product distributions and their GC-MS, NMR experimental results, the main formation temperature stages of the co-pyrolysis products are T1 and T2 respectively. The synergistic effects of T1 stage mainly consist of the catalytic effect of minerals in oil shale and the effect of micro-molecule free radicals on kerogen macromolecular restructuring process, while the synergistic effect of T2 stage comes from the catalysis of bio-char on the cracking process of the critical bitumen. Moreover, the synergistic effects significantly enhanced the H/C atomic ratio from 1.571 to 1.668 in bio-oil, causing a transfer of oxygen from pyrolytic oil to pyrolysis gas and promoting the generation of long straight carbon chains in shale oil.

Study on effects of molecule structure on exhaust emissions from RCCI engine fueled with low alcohol isomers

Due to the existence of reactivity stratification in mixture of Reactivity Controlled Compression Ignition (RCCI) engine, effects of molecule structure of low alcohols on exhaust emissions may be different. Three kinds of molecule structure, hydroxyl group position (OHP), methyl branches (MB) and straight carbon chain (SCC) are constructed through propanol and butanol isomers, and experimental data of exhaust emissions were drawn from RCCI engine under different oxygen mass contents (RO) and start of injections (SOI). Then, changes of exhaust emissions with OHP, MB, SCC, RO and SOI, and real influence factors and influence sequence of them on emissions are analyzed. The results show that: Although a certain emission changes with a certain impact factor, they may not be correlated with each other, which means the determination of real influencing factors and influence sequence is necessary. This determination is helpful to find out the strongest correlation influencing factors to optimize exhaust emissions. It is worth noting that, different emissions have different real influencing factors. NOX emission and particle mass concentration (PMC) are unrelated to molecule structure. On the contrary, they are only correlated to SOI. Moreover, all emissions are unrelated to OHP, and only HC emission is correlated to MB, while SCC is correlated to multiple emissions, and emission types correlated to Ro and SOI are the most.

Quantitative structure-pungency landscape of sanshool dietary components from Zanthoxylum species

The molecular basis of the pungency of sanshool dietary components from the Zanthoxylum species has been firstly addressed by constructing the statistically significant and highly predictive quantitative structure-pungency relationship models along with the pharmacophore models. The important pungent structural characters in the isobutylamide moiety and linear carbon chains were elucidated in this study that maintained the suitable spatial packing and electrostatic interactions with their receptors. Our results also revealed that the amide moiety, N-isobutyl moiety with suitable bulky and restricted electronegative substituents, and the relatively long straight carbon chains with suitable (conjugated) CC bonds or heteroatoms at regular intervals were essential for the high pungency. The pungency of 42 new sanshools was predicted, compared with the rough experimental data, and ultimately classified into weak, medium and strong types. Most of these sanshools were found to have good oral bioavailability and acceptable pharmacokinetic properties.

Quantum chemical calculations for the H free radical chemisorption with different chain models during oil shale pyrolysis

In this paper, the authors conduct an in-depth investigation for the thermochemical reaction of organic carbon and H free radical during oil shale retorting process. A set of carbon chain and reaction models were constructed and calculated through the transition state theory (TST) of quantum chemistry with Gaussian-16 package. The effect of functional groups during the reactions was explored through the density functional theory (DFT) at the B3LYP/6-311G (d) level. To make the calculation results more trustful and reliable, we choose reasonably simplified straight carbon chain models and construct the corresponding multiple reaction paths, which could elucidate the mechanisms of the thermochemical reaction. In the presence of H free radical, the cracking process of carbon chains in kerogen is promoted because of lower energy barriers. The charge re-distribution causing by the functional group also changes the H adsorption capacity of the organic carbons in different positions (α, β, γ, etc.). Moreover, different measuring methods of the rate constants are evaluated in this paper. The results could provide direct insight into the limitation of the conventional transition state theory (TST), which deserves more attention in further theoretical research.

Polymorphism of V-amylose cocrystallized with aliphatic diols

Chain-folded lamellar crystalline complexes of amylose with aliphatic diols were prepared and characterized by transmission electron microscopy as well as electron and X-ray diffraction. Four allomorphs were identified, depending on the complexing diol and crystallization conditions, that consisted of orthorhombic lattices of antiparallel 6- or 7-fold amylose single helices. Straight-chain n-diols (ethane-1,2-diol, butane-1,4-diol, hexane-1,6-diol) yielded 6-fold helical complexes regardless the length of the linear chain, whereas a bulkier branched diol (2-methylpentane-2,4-diol) induced the formation of 7-fold helices. Butane-1,3-diol, that contains a straight carbon chain with one end and one side hydroxyl group, induced both 6- and 7-fold helical conformations depending on the crystallization conditions. When a diol induced more than one allomorph, an adequate control of its concentration and crystallization temperature allowed targeting a specific crystalline form. Upon drying, all allomorphs were converted into more compact pseudo-hexagonal structures. The dried form of a given complex generally retained the same helical conformation as the hydrated one.

Influence of calophyllum inophyllum and Jojoba oil methyl ester blended with n-pentanol additive upon overall performance, combustion and emission characteristics of a TDI engine operated in natural aspirated mode

The present manuscript briefly elaborates the performance, combustion and emission behaviour of a turbocharged direct injection diesel engine operated in dual mode where calophyllum inophyllum and Jojoba oil methyl ester are the injected fuel while in second case the above said test fuel blends were mixed homogeneously with n-pentanol that acts as an additive during the experimentation. The main objective of using n-pentanol is its five straight chain carbon atoms that has better possibility of homogeneous blending with biodiesel blends due to its high cetane number, stability and density in contrast to other alcohol based additives helping in improving engine performance and diminished exhaust emissions. During the experimentation, engine parameters like compression ratio (17.5:1), injection timing (21°bTDC), injector opening pressure (220 bar), speed (1500 rpm) were kept constant. Results concluded CIME20–P20 blend to be reliable and potential alternative fuel to partially replace conventional diesel fuel. Considering performance and emission characteristics calophyllum inophyllum oil methyl ester and pentanol blend (CIME20–P20) depicts a higher brake specific fuel consumption of 3.41% while lower exhaust gas temperature and brake thermal efficiency of 13.46% and 1.18% in contrast to diesel fuel. Moving on to emission analysis, carbon dioxide, hydrocarbon, oxides of nitrogen and smoke opacity for CIME20–P20 were 57.02%, 59.37%, 17.39% and 41.53% lower than conventional diesel fuel. Hence, coming to the overall summary, CIME20–P20 depicts better performance and diminished exhaust emission thereby making it more potential to substitute the conventional fuel without any engine alteration for better environmental sustainability and energy security.

Electric field assisted alignment of monoatomic carbon chains

We stabilize monoatomic carbon chains in water by attaching them to gold nanoparticles (NPs) by means of the laser ablation process. Resulting nanoobjects represent pairs of NPs connected by multiple straight carbon chains of several nanometer lengths. If NPs at the opposite ends of a chain differ in size, the structure acquires a dipole moment due to the difference in work functions of the two NPs. We take advantage of the dipole polarisation of carbon chains for ordering them by the external electric field. We deposit them on a glass substrate by the sputtering method in the presence of static electric fields of magnitudes up to 105 V/m. The formation of one-dimensional carbyne quasi-crystals deposited on a substrate is evidenced by high-resolution TEM and X-ray diffraction measurements. The original kinetic model describing the dynamics of ballistically flowing nano-dipoles reproduces the experimental diagram of orientation of the deposited chains.

Formation of non-oxygenated phase of bio-oil produced by copyrolysis of corn cobs and polypropylene plastic using zeolite catalysts at low heating rate

Thermal co-pyrolysis of corn cobs and polypropylene (PP) at low heating rate (thermal slow co-pyrolysis) has succeeded in separating bio-oil produced between oxygenated and non-oxygenated phases spontaneously. In co-pyrolysis, PP can sequester oxygen from bio-oil to convert part of bio-oil to non-oxygenated phase and can contribute partly non-oxygenated phase by PP carbon chain cracking. Catalytic fast co-pyrolysis has been commonly used to improve bio-oil yield and to improve non-oxygenated fraction of bio-oil. However, the catalytic fast co-pyrolysis is unable to obtain separate non-oxygenated fraction of bio-oil. In present work, zeolite catalyst was introduced in co-pyrolysis of corn cobs and PP at low heating rate to undertake catalytic slow co-pyrolysis in order to obtain synergistic effect of non-oxygenated fraction of bio-oil while obtaining separate non-oxygenated fraction of bio-oil. The present co-pyrolysis work was carried out in a stirred tank reactor at heating rate of 5 °C/min and maximum temperature of 500 °C. The composition of feed was varied at 0, 50 and 100%PP in the mixture of corn cob particles and PP granules. The experiment involved 3 catalytic configurations, i.e., no catalyst, ZSM5-38 and ZSM5-70, in which 38 and 70 represents the mole ratio of SI/Al in the catalysts. The results show that in slow co-pyrolysis of biomass-PP, the use of zeolite catalyst with high acidity suppressed the pyrolysis of PP to form wax and reduced bio-oil yield, and the synergistic effect was obtained as the co-pyrolysis used no catalyst and zeolite catalyst of ZSM5-70, while that using zeolite catalyst of ZSM5-38 reached negative synergistic effect. Utilization of catalyst generated high amount of aliphatic moieties, i.e. methyl, methine and methylene. With ZSM5 catalyst utilization, production of allyl decreased. Most of non-polar bio-oil fractions have similar or slightly higher heating values (HHVs) compared to those of commercial fuels. Branching index (BI) values of non-polar phase of bio-oil generated straight carbon chain with higher branches compared to those commercial fuels.

Mechanism of Graphene Formation via Detonation Synthesis: ADFTB Nanoreactor Approach.

With the development of theoretical and computational chemistry, as well as high-performance computing, molecular simulation can now be used not only as a tool to explain the experimental results but also as a means for discovery or prediction. Quantum chemical nanoreactor is such a method which can automatically explore the chemical process based only on the basic mechanics without prior knowledge of the reactions. Here, we present a new method which combines the semiempirical quantum mechanical density functional tight-binding (DFTB) method with the nanoreactor molecular dynamic (NMD) method, and we simulated the reaction process of graphene synthesis via detonation at different oxygen/acetylene mole ratios. The formation of graphene is initiated by the breaking of acetylene (C2H2) molecules by collision into pieces such as H atoms, ethynyl (HC≡C•), and vinylidene (H2C═C:) radicals. It is followed by the formation of long straight carbon chains coupled with a few branched carbon chains, which then turned intoa2-D framework made of carbon rings. Trace oxygen could modulate the size of the rings during graphene formation and promote the formation of regular graphene with fused six-membered rings as we see, but the addition of high oxygen content makes more C-containing species oxidized to small oxide molecules instead of polymerization. The calculation speed of the DFTB nanoreactor is greatly improved compared to the ab initio nanoreactor, which makes it a valuable option to simulate chemical processes of large sizes and long time scales and to help us uncover the "unknown unknowns".

Fates of water and salts in non-aqueous solvents for directional solvent extraction desalination: Effects of chemical structures of the solvents

Non-aqueous solvents (NASs) are generally known to be barely miscible, and reactive with polar compounds, such as water. However, water can interact with some NASs, which can be used as a new means for water recovery from saline water. This study explored the fate of water and salt in NAS, when saline water is mixed with NAS. Three amine solvents were selected as NAS. They had the same molecular formula, but were differentiated by their molecular structures, as follows: 1) NAS \'A\' having the hydrophilic group (NH2) at the end of the straight carbon chain, 2) NAS \'B\' with symmetrical structure and having the hydrophilic group (NH) at the middle of the straight carbon chain, 3) NAS \'C\' having the hydrophilic group (NH2) at the end of the straight carbon chain but possessing a hydrophobic ethyl branch in the middle of the structure. In batch experiments, 0.5 M NaCl water was blended with NASs, and then water and salt content in the NAS were individually measured. Water absorption efficiencies by NAS \'B\' and \'C\' were 3.8 and 10.7%, respectively. However, salt rejection efficiency was 98.9% and 58.2%, respectively. NAS \'A\' exhibited a higher water absorption efficiency of 35.6%, despite a worse salt rejection efficiency of 24.7%. Molecular dynamic (MD) simulation showed the different interactions of water and salts with each NAS. NAS \'A\' formed lattice structured clusters, with the hydrophilic group located outside, and captured a large numbers of water molecules, together with salt ions, inside the cluster pockets. NAS \'B\' formed a planar-shaped cluster, where only some water molecules, but no salt ions, migrated to the NAS cluster. NAS \'C\', with an ethyl group branch, formed a cluster shaped similarly to that of \'B\'; however, the boundary surface of the cluster looked higher than that of \'C\', due to the branch structure in solvent. The MD simulation was helpful for understanding the experimental results for water absorption and salt rejection, by demonstrating the various interactions between water molecules and the salts, with the different NAS types.

Insights Into the Effect of Verticillium dahliae Defoliating-Pathotype Infection on the Content of Phenolic and Volatile Compounds Related to the Sensory Properties of Virgin Olive Oil.

Verticillium wilt, caused by the defoliating pathotype of Verticillium dahliae, is the most devastating soil-borne fungal disease of olive trees, and leads to low yields and high rates of tree mortality in highly susceptible cultivars. The disease is widely distributed throughout the Mediterranean olive-growing region and is one of the major limiting factors of olive oil production. Other than effects on crop yield, little is known about the effect of the disease on the content of volatile compounds and phenolics that are produced during the oil extraction process and determine virgin olive oil (VOO) quality and commercial value. Here, we aim to study the effect of Verticillium wilt of the olive tree on the content of phenolic and volatile compounds related to the sensory properties of VOO. Results showed that synthesis of six and five straight-chain carbon volatile compounds were higher and lower, respectively, in oils extracted from infected trees. Pathogen infection affected volatile compounds known to be contributors to VOO aroma: average content of one of the main positive contributors to VOO aroma, (E)-hex-2-enal, was 38% higher in oils extracted from infected trees, whereas average content of the main unpleasant volatile compound, pent-1-en-3-one, was almost 50% lower. In contrast, there was a clear effect of pathogen infection on the content of compounds responsible for VOO taste, where average content of the main bitterness contributor, oleuropein aglycone, was 18% lower in oil extracted from infected plants, and content of oleocanthal, the main contributor to pungency, was 26% lower. We believe this is the first evidence of the effect of Verticillium wilt infection of olive trees on volatile compounds and phenolics that are responsible of the aroma, taste, and commercial value of VOO.

Perspective: interesterified triglycerides, the recent increase in deaths from heart disease, and elevated blood viscosity.

The authors hypothesize that consumption of interesterified fats may be the cause of the continuous increase in cardiovascular deaths in the United States which began in 2011. Interesterification is a method of producing solid fats from vegetable oil and began to supplant partial hydrogenation for this purpose upon recognition of the danger of trans fats to cardiovascular health. Long, straight carbon chains, as are present in saturated and trans fatty acids, decrease the fluidity of the erythrocyte cell membrane, which decreases erythrocyte deformability and increases blood viscosity. This decrease in cell membrane fluidity is caused by increased van der Waals interactions, which also solidify dietary fats. Elevated blood viscosity is favored as the pathogenic mechanism by which trans fats increase cardiovascular mortality because changes in lipoprotein levels do not account for all the mortality attributable to their consumption. The rapid changes in cardiovascular mortality noted with the introduction and withdrawal of trans fats from the food supply are reviewed. The evidence implicating elevated blood viscosity in cardiovascular disease is also reviewed. Data regarding the production and consumption of interesterified fats in the US should be released in order to determine if there is an association with the observed increase in cardiovascular deaths.

Mesoporous Akaganeite of Adjustable Pore Size Synthesized using Mixed Templates

Mesoporous akaganeite with large and adjustable pore size was synthesized through a co-template method, which was achieved by the combined interaction between PEG2000 and alkyl amines with different lengths of the straight carbon chain. The characterized results indicate that the synthesized samples show comparatively narrow BJH pore size distributions and centered at 14.3 nm when PEG and HEPA was used, and it could be enlarged to 16.8 and 19.4 nm respectively through changing the alkyl amines to DDA and HDA. Meanwhile, all the synthesized akaganeite possess relativity high specific surface area ranging from 183 to 281 m2/g and high total pore volume of 0.98 to 1.5 cm3/g. A possible mechanism leading to the pore size changing was also proposed.

Gold immunochromatographic sensor for the rapid detection of twenty-six sulfonamides in foods

A gold immunochromatographic sensor (GICS) was developed for the rapid detection of 26 sulfonamides in honey samples. The sensor was based on a group-specific monoclonal antibody (mAb) that can recognize all 26 sulfonamides. Three haptens (hapten 1 with a thiazole ring, hapten 2 with a benzene ring, and hapten 3 with a straight carbon chain) were used for antigen preparation. With hybridoma technology, a group-specific mAb was screened with a 50% maximal inhibitory concentration (IC50) against sulfathizole (STZ) and the other 25 analogues ranging from 0.08 to 90.18 ng/mL. Mono-dispersed gold nanoparticles were conjugated with the mAb to develop the lateral immunochromatographic strip. A labeled antibody concentration of 0.1 μg/mL and a coating antigen concentration of 0.2 μg/mL in the test line were chosen for strip preparation. Under optimized conditions, the visual limits of detection (vLOD) for the concentrations of STZ, sulfamethoxazole, sulfamethizole, sulfadiazine, sulfamerazine, sulfadimethoxine, sulfamonomethoxine, sulfameter, sulfamethoxypyridazine, and sulfachloropyridazine were 5, 0.25, 0.25, 10, 5, 10, 25, 2.5, 5, 0.25, and 10 μg/kg, respectively. Scanner analysis in honey samples revealed good performance for detection of the 26 sulfonamides. Commercial honey samples were tested with the sensor and positive results were confirmed with high-performance liquid chromatography. The proposed strip sensor provides a convenient method for the rapid and reliable determination of sulfonamides pollutants in honey samples.

Volatile Compound Profiling by HS-SPME/GC-MS-FID of a Core Olive Cultivar Collection as a Tool for Aroma Improvement of Virgin Olive Oil.

Virgin olive oil (VOO) is the only food product requiring official sensory analysis to be classified in commercial categories, in which the evaluation of the aroma plays a very important role. The selection of parents, with the aim of obtaining new cultivars with improved oil aroma, is of paramount importance in olive breeding programs. We have assessed the volatile fraction by headspace-solid-phase microextraction/gas chromatography-mass spectrometry-flame ionization detection (HS-SPME/GC-MS-FID) and the deduced aroma properties of VOO from a core set of olive cultivars (Core-36) which possesses most of the genetic diversity found in the World Olive Germplasm Collection (IFAPA Alameda del Obispo) located in Cordoba, Spain. The VOO volatile fractions of Core-36 cultivars display a high level of variability. It is mostly made of compounds produced from polyunsaturated fatty acids through the lipoxygenase pathway, which confirms to be a general characteristic of the olive species (Olea europaea L.). The main group of volatile compounds in the oils was six straight-chain carbon compounds derived from linolenic acid, some of them being the main contributors to the aroma of the olive oils according to their odor activity values (OAV). The high level of variability found for the volatile fraction of the oils from Core-36 and, therefore, for the aroma odor notes, suggest that this core set may be a very useful tool for the choice of optimal parents in olive breeding programs in order to raise new cultivars with improved VOO aroma.

A new class of draw solutions for minimizing reverse salt flux to improve forward osmosis desalination

The applications of forward osmosis (FO) have been hindered because of the lack of an optimal draw solution. The reverse salt flux from the draw solution not only reduces the water flux but also increases the cost of draw solute replenishment. Therefore, in this study, Tergitol NP7 and NP9 with a long straight carbon chain and low critical micelle concentration (CMC) were coupled with highly charged ethylenediaminetetraacetic acid (EDTA) as an innovative draw solution to minimize reverse salt diffusion in FO for the first time. The results showed that the lowest reverse salt flux of 0.067 GMH was observed when 0.1M EDTA-2Na coupled with 15mM NP7 was used as a draw solution and deionized water was used as a feed solution in FO mode (active layer facing with the feed solution). This is due to the hydrophobic interaction between the tails of NP7 and the FO membrane, thus creating layers on the membrane surface and constricting the FO membrane pores. Moreover, 1M EDTA-2Na coupled with 15mM NP7 is promising as an optimal draw solution for brackish water and sea water desalination. Average water fluxes of 7.68, 6.78, and 5.95 LMH were achieved when brackish water was used as a feed solution (5, 10, and 20g/L NaCl), and an average water flux of 3.81 LMH was achieved when sea water was used as a feed solution (35g/L NaCl). The diluted draw solution was recovered using a nanofiltration (NF-TS80) membrane with a high efficiency of 95% because of the high charge and large size of the draw solution.

Low-Cost Synthesis and Characterizations of Metal-Organic Framework (MOF-199) Materials by Nonsurfactant Templating Method

In this study, a three-dimensional (3D) copper-based metal-organic framework (MOF-199) is a microporous materials with structural formula Cu3(BTC)2 (1,3,5-benzene tricarboxylate) were successfully synthesized using nonsurfactant templating method. The preparations of MOF-199 utilized different length of straight carbon chain (oleochemical) fatty alcohols derived from palm oil were similar to those reported earlier by our group with some modifications [1]. This new method led to unique structure and properties of as-synthesized MOF-199. The addition of fatty alcohols such as octyl (C8) and decyl (C10) alcohol act as renewable template onto MOF-199 generating the required carbon template for microporous crystalline structure [2]. The MOF-199 had been synthesized using conventional hydrothermal method with the present of fatty alcohols to analyse the resulting MOF-199 in terms of structure, morphology, surface area and adsorption isotherm. MOF-199 synthesized in this study exhibited single crystal orthorhombic morphology at ca. 30 micron. The crystallinity of MOF-199 materials was improved by the addition of fatty alcohols as observed in the X-Ray Diffraction patterns.
