Facile synthesis of Aluminium fumarate metal–organic framework and hydroxyapatite composite with improved adsorption characteristics for efficient fluoride removal from water

An aluminium fumarate (AlFu)-hydroxyapatite (HAP) composite (AlFu-HAP) with numerous functional groups for fluoride binding was synthesised by a simple solid–solid mixing process. The produced AlFu-HAP composite with numerous functional groups results in outstanding adsorption capability in the sequence AlFu-HAP > AlFu > HAP. This composite was studied under different pH, initial fluoride concentrations, temperatures, and contact times. The adsorption kinetics and isotherms were pseudo-second-order model and Freundlich adsorption isotherm, respectively. XRD, SEM, FTIR, Raman spectroscopy, and XPS analysis of the samples before and after the adsorption reaction indicate that the fluoride removal mechanism was controlled by anion exchange of the OH– group in AlFu-HAP and F- in water. At high concentrations (150–200 mg F-/L) in groundwater and industrial effluent, the AlFu-HAP showed > 90 % fluoride removal. Thus, the current study will provide an effective strategy for developing an AlFu-HAP composite adsorbent to be used for the effective elimination of fluoride from wastewater.

Thermodynamic Analysis and Performance Assessment of a Novel Solar-Based Multigeneration System for Electricity, Cooling, Heating, and Freshwater Production

Abstract This study offers a comprehensive assessment of the thermodynamic performance of a novel solar-based multigeneration system, which caters to the energy needs of a sustainable community by producing electricity, cooling, heating, and freshwater. The solar-based multigeneration system is comprised of four main components: the thermal subsystem of the parabolic trough collector (PTC) employing CO2 as a heat transfer fluid, a single-effect absorption refrigeration cycle (ARC), a supercritical CO2 (S-CO2) cycle, and an adsorption desalination (AD) cycle with heat recovery employing aluminum fumarate metal–organic framework (MOF) adsorbent material. A comprehensive parametric study was performed on the proposed solar-based multigeneration system by varying key parameters to evaluate its performance. It is found that the thermal and exergy efficiencies of a PTC were evaluated to be 68.35% and 29.88%, respectively, at a fixed inlet temperature of 225 °C and solar irradiation of 850 W/m2 and also a slight reduction in the ARC cycle when examining the variation in the thermal and exergetic COPs for the generator temperature. Additionally, the thermal and exergy efficiencies of electricity, cooling, and heating were determined to be 20.41% and 21.93%, 41.34% and 3.51%, and 7.14% and 3.07%, respectively, at the operating condition. The maximum specific daily water production (SDWP) value of 12.91 m3/ton/day and a gain output ratio (GOR) of 0.64 were obtained under steady operating conditions in the AD cycle.

Development and assessment of a novel integrated system powered by parabolic trough collectors for combined power, heating and freshwater production

Abstract Hybrid solar-based integrated systems represent a viable solution for countries with abundant solar radiation, as they provide energy needs in an environmentally friendly way, offering a sustainable and economically advantageous energy solution that utilizes a free source of energy. Therefore, this research offers a thermodynamic evaluation of a novel integrated system driven by solar energy that aims to produce power, heating and freshwater. The integrated system consists of a parabolic trough collector that uses CO2 as its working fluid and implements the supercritical carbon dioxide cycle to generate power and heating. The integrated system also includes an adsorption desalination system with heat recovery between the condenser and evaporator, which employs a cutting-edge material called an aluminium fumarate metal–organic framework to produce fresh water. For the modelling of a novel system, an engineering equation solver, which is considered a reliable tool for thermodynamic investigations, is employed. The effectiveness of an integrated system is evaluated using a mathematical model and different varying parameters are examined to ascertain their influence on thermal and exergy efficiency, specific daily water production and gained output ratio. The results revealed that the parabolic trough collector achieved a thermal efficiency of 67.2% and an exergy efficiency of 41.2% under certain conditions. Additionally, the thermal efficiencies for electrical and heating were obtained 24.68% and 9.85%, respectively. Finally, the specific daily water production was calculated, showing promising results and an increase from 7.1 to 12.5 m3/ton/day, while the gain output ratio increased from 0.395 to 0.62 when the temperature of hot water increased from 65°C to 85°C, under the selected conditions.

Enhanced photo-degradation of organic contaminants on CdS/magnetic aluminum fumarate metal-organic framework as a novel Z-scheme photocatalyst under visible light: A comprehensive study

In the current study, Fe3O4/aluminum fumarate (AlFu) magnetic nanocomposite has been synthesized through the sol-gel procedure to be used as a novel support for CdS nanorods in photocatalytic degradation of Congo red (CR) and crystal violet (CV) dyes in aqueous media under visible light irradiation, separately. The CdS nanorods were solvothermally decorated on magnetic AlFu. The physicochemical properties of the synthesized samples were examined by multiple techniques. In comparison to pure CdS, the photocatalytic performance of magnetical separable Cd/magnetic AlFu is striking. This could be attributed to improving the recombination rate, charge transfer resistance, and adsorption site, which are figured out through characterization data. Removal of contaminants has been statistically optimized and modeled based on operational parameters, including catalyst dosage, initial dye concentration, and pH. At optimum conditions, the removal of CR and CV dyes was 99.5 % and 86.17 %, respectively. Moreover, the photocatalyst exhibited satisfactory performance in TOC removal and remarkable stability during six successive cyclic operations. At several dye concentrations, kinetic experiments have been undertaken, and results revealed that the photo-degradation reaction of CR and CV corresponds well with the Langmuir-Hinshelwood model. Furthermore, the Z-scheme mechanism was suggested based on characterization data and quenching experiments, which revealed that •O2- plus h+ in CR photo-degradation, and •O2- plus •OH in CV photo-degradation play pivotal roles.

Towards High CO2 Conversions Using Cu/Zn Catalysts Supported on Aluminum Fumarate Metal-Organic Framework for Methanol Synthesis

Green methanol is a viable alternative for the storage of hydrogen and may be produced from captured anthropogenic sources of carbon dioxide. The latter was hydrogenated over Cu-ZnO catalysts supported on an aluminum fumarate metal-organic framework (AlFum MOF). The catalysts, prepared via slurry phase impregnation, were assessed for thermocatalytic hydrogenation of CO2 to methanol. PXRD, FTIR, and SBET exhibited a decrease in crystallinity of the AlFum MOF support after impregnation with Cu-Zn active sites. SEM, SEM-EDS, and TEM revealed that the morphology of the support is preserved after metal loading, where H2-TPR confirmed the presence of active sites for hydrogen uptake. The catalysts exhibited good activity, with a doubling in Cu and Zn loading over the AlFum MOF, resulting in a 4-fold increase in CO2 conversions from 10.8% to 45.6% and an increase in methanol productivity from 34.4 to 56.5 gMeOH/Kgcat/h. The catalysts exhibited comparatively high CO selectivity and high yields of H2O, thereby favoring the reverse water-gas shift reaction. The selectivity of the catalysts towards methanol was found to be 12.9% and 6.9%. The performance of the catalyst supported on AlFum MOF further highlights the potential use of MOFs as supports in the heterogeneous thermocatalytic conversion of CO2 to value-added products.

반응성 필러로써 Aluminum Fumarate을 이용한 Dicyanate Composites의 물성 강화: 열역학적 특성 연구

In this work, the synthesized nanoporous aluminum fumarate (Al_FA_A) metal organic framework (MOF) has been used as reactive filler for the bisphenol-A dicyanate (BADCy) resin system. The use of Al_FA_A is interesting due to the involvement of double bonds (fumarate) in triazine during polymerization. The thermal properties of the polymers formed with and without reactive filler were evaluated under different curing temperatures, prepolymerizations and post-polymerizations conditions. All the samples were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and X-ray diffraction analysis (XRD) and Evolved gas analysis. On the contrary, the cure chemistry was determined by non-isothermal model free kinetic methods. This study provides a new path to utilize the MOFs as reactive nanoparticle fillers to obtain multifunctional materials.

Sustainable green functional nano aluminium fumarate-MOF decorated on 3D low-cost natural diatoms for the removal of Congo red dye and fabric whitening agent from wastewater: Batch & continuous adsorption process

Industrial contaminants such as dyes being released into water streams, making the water unfit for the domestic purposes. Treatment of such dye contaminants still remains as a challenge which transformed as leading issues in environment remediation. Some of the important limitations involved in the dye adsorption includes cumbersome synthetic routes, high cost adsorbents, more contact time, lack of efficiencies and usage of more adsorbents. To address these drawbacks, present work involves facile surface modification of 3D diatoms (DE) with 2D aluminium fumarate metal-organic framework (Al-MOF) as a sustainable approach to obtain hybrid materials for the removal of industrial important toxic dyes. It is significant to note that the surface area of diatoms increased dramatically from 16.6 to 1330.8 m2g−1 revealing that the surface modifications with Al-MOF played a significant role in tuning the surface properties of DE. The developed hybrid materials were investigated for batch adsorption studies for the removal of CR dye which displayed outstanding 98.13% removal efficiency for just 20 mg of adsorbent with rapid contact time of 15 min. Moreover, the maximum adsorption capacity (qm) was found to be 181.82 mg/g, which is of better significance. Further, hybrid materials were adapted as powder-based membranes a continuous flow adsorption studies where 100 mg of materials showed excellent 99.65% of rejection performances with flux rate of 1747.1 Lm−2h−1. To demonstrate their capability in real-time sample analysis, 100 mg of hybrid materials were used for the removal of fabric whitening agent through batch adsorption and continuous flow studies exhibited with effective 94% and 99.2% efficiencies respectively. Additionally, the reusability test of adsorbents showed it could be used up to 6 cycles where the adsorbents can be regenerated with facile methanol wash. The developed hybrid materials could be one of the potential candidates for the removal of hazardous textile dye from wastewater since the adsorbent displayed rapid adsorption, efficient removal, utilization of minimal adsorbents, better reusability and finally substantiated with real time sample analysis.

Coated, packed and combined wire finned tube adsorption cooling and desalination system using metal-organic framework: Numerical study

The adsorber bed design and the method of integrating the adsorbent material in the bed have a major effect on the overall performance of the adsorption system. This study numerically investigates the performance of wire finned tube adsorber bed with aluminium fumarate metal-organic framework material integrated either using coating, packing, or combination of coating and packing. A 3D heat and mass transfer model using the coupled solution approach with a variable vapor pressure through the adsorbent voids between the particles is developed. Results showed that the coated wire finned heat exchanger outperforms the packed and the combined packed and coated in terms of the specific daily water production (SDWP) and specific cooling power (SCP). Also, a parametric study was carried out of the coated wire finned heat exchanger geometry including different tube diameters, fin height, and number of fins to predict the best geometrical parameters that produce maximum output using different coating thicknesses. Results revealed that using tube diameter of 22 mm, fin height of 20 mm, 44 fins per loop, and coating thickness of 0.5 mm can provide maximum water daily water production of 300 L/day and cooling power of 8.3 kW.

Dehumidification performance of aluminum fumarate metal organic framework and its composite

The output and adsorption characteristics of solid adsorbents limit their application in a desiccant wheel system. Therefore, this paper proposed a macroscopic green synthesis method for aluminum fumarate metal organic framework (approximately 400 g can be synthesized in a single time). By combining with other materials, the dehumidification performance of aluminum fumarate had been greatly improved. The microporous structure and dehumidification-desorption performance of the samples were analyzed by physical characterization and constant temperature and humidity chamber respectively. Results showed that at a relative humidity of 80%, the dehumidification capacity of the composite material reached 2.5 and 3.18 times that of aluminum fumarate and commercially silica gel, respectively. The composite material can also achieve a better desorption effect at a lower desorption temperature (50 ℃), with a desorption ratio of 82%. This proved that the composite material based on aluminum fumarate had great potential in the application.

Study of MOF incorporated dual layer membrane with enhanced removal of ammonia and per-/poly-fluoroalkyl substances (PFAS) in landfill leachate treatment

Landfill leachate is a highly polluted and complex wastewater as it contains large amounts of organic matters, ammonia‑nitrogen, heavy metals, and per−/poly-fluoroalkyl substances (PFAS), which makes its treatment very challenging. In this paper, hydrophilic/hydrophobic dual layer membranes combining advantages of pervaporation and membrane distillation was employed to treat leachate in a direct contact membrane distillation (DCMD) configuration. An aluminum fumarate (AlFu) metal organic framework (MOF) incorporated poly(vinyl alcohol) (PVA) hydrophilic layer was coated on hydrophobic PTFE membrane to overcome the low separation efficiency of PFAS and ammonia and wetting issues encountered by the conventional hydrophobic PTFE membrane used for DCMD. The rejections of dual layer membranes with different MOF loading to PFAS, ammonia, TOC and TDS were assessed based on the amount of AlFu MOF incorporated into the PVA layer. Based on the conducted adsorption tests, it was found that AlFu MOF increases the rejection of PVA layer to PFAS and ammonia. The coating of the hydrophilic layer could enhance the wetting resistance with/without MOF addition. In comparison with the pristine PTFE membrane using synthetic feed containing 3 wt% NaCl, 1 wt% addition of AlFu MOF into the PVA layer showed slightly increased flux. All the tested membranes showed more than 99% rejection to TOC. The rejection to ammonia was increased as more MOF was incorporated into the PVA layer. The maximum rejection of ammonia was 99.8% when the PVA layer containing 10% MOF. All the membranes showed more than 99% rejection to PFOS and PFHxS. However, PTFE membrane did not show any rejection to PFOA. As more MOF was added into the hydrophilic layer, the rejection to PFOA increased, but plateaued at 65.6% with 5% MOF incorporation into the hydrophilic layer.

• Mechanical properties of aluminium fumarate coating were experimentally tested. • Effect of coating thickness was investigated through a COMSOL model. • Operating conditions were investigated through an experimental parametric study. • Performance of aluminium fumarate coated and packed systems were compared. • Aluminium fumarate coated system outperformed packed one in cooling applications. This study discusses integrating aluminium fumarate metal-organic framework (MOF) as a coated layer instead of conventional packing to improve the adsorption system performance. The mechanical strength of the MOF coating layer was tested showing enhanced heat transfer properties and high durability. An experimental parametric study was conducted where parameters such as half-cycle time, evaporator water inlet, adsorption bed water inlet, condenser water inlet and desorption bed inlet temperatures were investigated and the coated heat exchanger performance was compared to conventional packing. Results showed that the aluminium fumarate coated heat exchanger had an optimum half-cycle of 500 s which is shorter than the packed one which was 900 s. Also, at a cycle time of 1000 s, the aluminium fumarate coated heat exchanger produced 600 W kg 1 which is three folds of what was produced from the packed one. The significant enhancement in the specific cooling power highlights the potential of integrating aluminium fumarate as a coated layer instead of packing.

Experimental testing of wire finned heat exchanger coated with aluminium fumarate MOF material for adsorption desalination application

Adsorption technology can supply both cooling and drinking water without using electricity as it can be operated using solar energy or waste heat sources. Commercially available adsorption systems utilize adsorbent porous materials such as zeolite and silica gel that suffer from high regeneration temperature for the former and lower hydrophilicity of the latter. To avoid these problems, aluminium fumarate metal-organic framework (MOF) material is used in this study as a promising new adsorbent material with water uptake higher than that of silica gel and zeolite. The material was integrated as a coated layer instead of the conventional granular form. The performance of the developed coated wire wound finned tube heat exchanger was compared with packed one using aluminium fumarate in adsorption cooling and desalination applications. Results showed that the performance of the coated heat exchanger outperformed the packed heat exchanger for both applications. For adsorption water desalination, the coated wire finned heat exchanger produced a specific daily water production (SDWP) of 23.5 m3/ton/day compared to only 12.7 m3/ton/day for packed heat exchanger. For adsorption cooling application, the coated wire finned heat exchanger produced a specific cooling power (SCP) and a coefficient of performance (COP) of 682 W/kg and 0.32 compared to 318.5 W/kg and 0.23 for packed heat exchanger.

Development of cellulose acetate-chitosan-metal organic framework forward osmosis membrane for recovery of water and nutrients from wastewater

Aluminium fumarate (AlFu) metal organic framework (MOF) incorporating forward osmosis (FO) membrane prepared by coating chitosan (CS)-AlFu MOF mix on cellulose acetate (CA) membrane. AlFu MOF in the membrane separation layer enhanced hydrophilicity and resulted in higher water flux and lower reverse salt flux than CA or the CA-CS membranes. The M-1–0.06 membrane with 1% CS coating and 0.06 wt% AlFu MOF addition identified to be optimal. Using MgCl2.6 H2O as the draw, the membranes tested for concentration of nutrients from synthetic wastewater (SW) and real wastewater (RW) from a cowshed. For the SW feed, M-1–0.06 displayed enhanced water flux (18 LMH compared to 11.8 LMH for CA membrane) and accumulation (concentration) of components as follows: COD (2X), NH4-N (1.9X), NO3-N (0.76X) and PO4 (0.85X). With RW feed, the water flux was lower (8.75 LMH), but components concentration was higher: COD (3.75X), NH4-N (4.46X), NO3-N (3.35X) and PO4 (5.1X). Fouling due to cake layer deposits on the membrane surface could be removed by physical cleaning. Over 80% water recovery obtained in FO, and 85% salt rejection was obtained from diluted draw solution using reverse osmosis (RO). The nutrients in concentrated feed wastewater recovered as struvite (NH4MgPO4.6 H2O) by precipitating, using the RO reject, which was also the re-concentrated draw solution for the next FO experiment.

Performance of a solar adsorption cooling and desalination system using aluminum fumarate and silica gel

• Aluminum Fumarate is evaluated in a solar hybrid cooling and desalination system. • The comparison with silica gel spotlights the net effects of a dynamic heat source. • Interrelated effects of thermal and adsorption characteristics are critical issues. • Aluminum Fumarate performance is affected negatively by the cumulative heat stored. • Silica gel system is more responsive to changes in the initial heating temperature. This paper numerically investigated the influence of adsorbent materials’ thermal and adsorption characteristics on the overall performance of solar adsorption cooling cum desalination systems. A case study using an array of solar collectors was conducted to compare the emerging Aluminum Fumarate metal–organic framework (Al-Fum) with conventional silica gel (SG) under typical meteorological data at a selected site. Although the adsorption characteristics of Al-Fum outperforms SG at the material level, the former’s low thermal characteristics increased the cumulative heat stored and limited the integrated-system performance. The low thermal diffusivity of Al-Fum slowed down the integrated system’s response, providing that the average solar COPs of the SG-based system over different months were higher by 83%, 43%, and 22% at inlet chilled water temperatures of 15 °C, 20 °C, and 25 °C, respectively, and 1 mm fin spacing. However, the best specific cooling power of the AF-based system were higher than those of the SG-based system by − 16.6%, 16.8%, and 30.5% at these temperatures. Furthermore, the SG-based system was more negatively affected by reducing the heat storage initial temperature from 70 °C to 50 °C, but it attained COP and solar COP higher than those of the AF-based system by 14.9%–63%, respectively.

The prepared MOF was characterized using the XRD and FTIR spectra, as well as SEM images and TGA. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques were used to evaluate the inhibitor performance in a concentration range of 50-400 ppm. The results indicated that the inhibition efficiency enhanced with increasing inhibitor concentration and reached 88.35% at 400 ppm, indicating the high potential of the proposed MOF.

In Situ Polymerization of Polypyrrole @ Aluminum Fumarate Metal–Organic Framework Hybrid Nanocomposites for the Application of Wastewater Treatment

Composite metal–organic frameworks combine large and accessible surface areas with low density and high stability. Herein, we present novel nanocomposites of polypyrrole/aluminum fumarate metal–organic framework (PPy/AlFu MOF), which were synthesized via in situ oxidative polymerization with the aim of MOF functionalization to enhance its thermal stability and increase the specific surface area so that these nanocomposites may be used as potential adsorbents. The synthesized nanocomposites were characterized by various techniques, such as powder X-ray diffraction, scanning electron microscopy, and Fourier-transform infrared spectroscopy (FTIR). The successful functionalization of aluminum fumarate MOF was confirmed by FTIR, and the Brunauer–Emmett–Teller (BET) surface area of the PPy/MOF nanocomposite slightly increased from 795 to 809 . Thermogravimetric analysis data also show that the weight loss of the composite is up to 30% at temperatures up to 500 . Remarkably, lead (50 ppm) sequestration using the composite was tested, and the atomic absorption spectrometry data demonstrate that PPy/MOF is a super-adsorbent for heavy metal ions. This work shows that the novel polymer–MOF composites are promising materials for the selective removal of lead from wastewater streams.

CO2 cycloaddition to epichlorohydrin over an aluminum fumarate metal-organic framework synthesized by a sonochemical route

Aluminum fumarate was tested as a catalyst for CO 2 cycloaddition to epichlorohydrin under solvent-free reaction conditions. This material was synthesized hydrothermally via a sonochemical route (Al fumarate-(S)), which exhibited a higher catalytic activity than Al fumarate synthesized by a conventional method owing to the higher number of Lewis acid sites formed in Al fumarate-(S). The CO 2 uptake of Al fumarate-(S) was high: approximately 269 mg g −1 at 25 °C and 10 bar. High conversion (96%) of epichlorohydrin with excellent selectivity (97%) to cyclic carbonate was obtained at 50 °C and 10 bar CO 2 after 6 h of reaction. The kinetic analysis of the reaction confirmed an approximately 1st order dependence on the epichlorohydrin concentration and CO 2 pressure with an activation energy of approximately 39 kJ mol −1 . The recovered Al fumarate-(S) catalyst, however, showed a steady decline in catalytic activity during the recycling runs, as reported for other metal-organic framework catalysts. The deactivation was monitored by N 2 adsorption-desorption isotherms and spectroscopic analyses. • The aluminum fumarate metal-organic framework was synthesized via a sonochemical route. • It showed higher amounts of Lewis acid sites and more active for CO 2 cycloaddition than the one conventionally prepared. • A reaction mechanism for CO 2 cycloaddition to epichlorohydrin was proposed.

Experimental testing of aluminium fumarate MOF for adsorption desalination

Many researchers consider adsorption systems as a solution for global problems such as global warming and water scarcity. The experimental and numerical data available in literature are basically focusing on using conventional adsorbent materials such as silica gel and zeolites. Recently, metal-organic framework (MOF) materials have been proposed to substitute these conventional adsorbents. Nevertheless, the potential of MOFs has been only numerically investigated without any experimental data from a real system. To fill this research gap, this work presents for the first time the experimental testing of a MOF material, aluminium fumarate, and how it can enhance the performance of adsorption desalination systems. A parametric study to investigate the effect of different parameters such as chilled water, adsorption cooling water, condensation cooling water, desorption heating water temperatures and half cycle time on the performance of the adsorption system has been conducted. The suitability of the aluminium fumarate system for adsorption desalination was also assessed through analysing the quality of water produced from the system. Finally, the performance of the aluminium fumarate was also compared to conventional adsorbents such as silica gel. The superior performance of aluminium fumarate highlights the potential of the material in adsorption desalination application.

Decorated graphene with aluminum fumarate metal organic framework as a superior non-toxic agent for efficient removal of Congo Red dye from wastewater

Nowadays, disposal of highly stable toxic dyes into the ecosystem and water sources has become a great concern for our health, while many attempts were conducted to remove these kinds of pollutants from the ecosystem through practical scientific protocols. Herein, for the first time, we decorated the graphene oxide (GO) and reduced graphene oxide (rGO) with the highly porous aluminum fumarate (AlF) metal organic framework (AlF MOF) toward efficient and high yield removal of the Congo Red (CR) dye ((3,3′-([1,1′-biphenyl]z-4,4′-diyl)bis(4-aminonaphthalene-1-sulfonic acid)) as a severely toxic and even carcinogenic substance from aqueous media. In this case, developed absorbers including AlF, AlF-GO and AlF-rGO were well-characterized through diverse analyses that confirmed their successful synthesis and also superior specific surface area and porosity, where their respective BET surface areas found to be 973.39, 917.79 and 951.88 m2. g−1. Additionally, outcome of further analyses showed that the experimental data are well fitted with Langmuir isotherm and pseudo-second-order kinetic model which show that the absorption process occur through chemisorption via uniform energetic absorption sites. Further evaluations showed that the AlF and its derived composites with GO and rGO can completely remove the CR dye at optimum conditions (more than 99% yield) and reach to the absorption capacity of about 93.45, 102.04 and 178.57 mg.g−1 for concentrations between 1–40 μg.mL−1 at optimum conditions, which highlight their superior sensitivity. Additionally, for the first time it was also reported that the AlF composite with GO is fully non-toxic.
