Engineering unsaturated sulfur site in three-dimension MoS2@rGO nanohybrids with expanded interlayer spacing and disordered structure for gaseous elemental mercury trap

Rapid and effective capture of gaseous elemental mercury (Hg0) over a wide operating temperature range is significant for the green and sustainable development of nonferrous smelting industry. High mercury affinity and strong sulfur resistance of two-dimensional layered MoS2 render it an outstanding adsorbent for Hg0 trap. However, the relative lack of serviceable active sites greatly suppresses its extensive application. Herein, a feasible strategy to expand interlayer spacing, build disordered structure and engineer unsaturated sulfur adsorption sites was provided through the construction of three-dimension MoS2@rGO nanohybrids. As expected, compared with bulk and ordered MoS2, the prepared MoS2@rGO hybrid exhibits a remarkable performance improvement for Hg0 adsorption. The average Hg0 adsorption rate of MoS2@rGO is 2.28 μg/g/min and its saturated adsorption capacity reaches 20.91 mg/g. The typical components in nonferrous flue gas have almost no effect on Hg0 adsorption performance. X-ray photoelectron spectroscopy confirms that the formation of abundant unsaturated coordination sulfurs sites with high thermostability is critical for Hg0 adsorption performance improvement. Moreover, the density functional theory calculation results further demonstrate the high adsorption activity of unsaturated coordination sulfur sites for Hg0 capture. Among these sulfur sites, edge sulfur vacancy site plays a dominant role for Hg0 adsorption because of the lowest Hg0 adsorption energy. The final adsorption production is HgS which has negligible environmental toxicity due to its extreme stability. This work not only provides a promising adsorbent for Hg0 removal in industrial application, but also opens up an avenue to engineer unsaturated sulfur for other layered transition metal dichalcogenides.

Magnetic Fe3O4/ZIF-8 composite as an effective and recyclable adsorbent for phenol adsorption from wastewater

Recovery of phenol in wastewater is a matter of concern. Metal organic frameworks (MOFs) are promising adsorbents for the removal of organic pollutants from water phase owing to their rich pore structure and high chemical activity. However, most MOFs are in the form of microcrystalline powders, making them difficult to be separated and recycled. Therefore, it is important to explore the facile fabrication of magnetic adsorbents with high adsorption efficiency, fast equilibrium adsorption time, and excellent recoverability. A regenerable magnetic Fe3O4/ZIF-8 composite was prepared for phenol removal with ZIF-8 as adsorption mainstay and Fe3O4 nanoparticle as magnetic component. Through self-assembly process design, the advantages of the combination and its synergistic effect were exhibited. The effects of pH, binding time, and initial concentration on the adsorption behaviors of Fe3O4/ZIF-8 towards phenol were investigated to assess adsorption capacity and reusability. Owing to the dual effect of high adsorption activity and abundant pore structures, Fe3O4/ZIF-8 demonstrated prominent adsorption capacity (129.8 mg g−1) and rapid adsorption rate (20 min) towards phenol. The pseudo-second-order kinetic model fits the adsorption data well. The thermodynamic adsorption curves conform to the Langmuir model. The adsorption mechanism involves the critical contribution of hydrogen bonding interaction, π-π interaction, pore adsorption, and electrostatic attraction. Moreover, the magnetic adsorbent shows excellent reusability. This work provides a new sight on the synthesis of high efficiency adsorbents for organic pollutant separation.

Efficient capture of ornidazole through cobalt/zinc-containing naonoporous carbons derived from cobalt/zinc-based MOF-74

Ornidazole (ONZ) capture from water is one of thorny difficulties for water purification. To solve this issue, a series of novel interconnected nano-porous carbons (NPCs) with high adsorption activities toward ONZ has been firstly developed via direct carbonization of Zn-(MOF-74), Co-(MOF-74), and Zn/Co-(MOF-74) self-sacrifice templates. Textural properties of as-prepared NPCs were proven and compared by XRD, SEM, XPS, and N2 adsorption, etc. The extraordinary 3D porous structure thus fabricated significantly enhanced ONZs capture ability. Inspiring, we observed that Zn/Co-NPC exhibited extraordinarily high ONZs capture capacity as a result of synergistic effects of electrostatic interactions, hydrogen bonding, coordination, and π-π conjugation, displaying a maximum ONZs uptakes capacity of 320 ​mg/g. Moreover, the ONZs capture ability over our prepared NPCs only underwent a slight change after the fifth reuse. Overall, this novel NPC exhibits a promising practical application for ONZs capture from aqueous solutions.

ИССЛЕДОВАНИЕ АДСОРБЦИОННЫХ СВОЙСТВ УГЛЕРОДНЫХ СОРБЕНТОВ МЕДИЦИНСКОГО И ВЕТЕРИНАРНОГО НАЗНАЧЕНИЙ

In this work, the parameters of the porous structure and adsorption properties of carbon enterosorbents Zoocarb and SUMS-1 were studied. Organic dyes methylene blue and methanyl yellow were used as substances simulating toxic compounds of low molecular weight. It has been established that the carbon enterosorbent Zoocarb has a high adsorption activity with respect to these substances compared to SUMS-1. The nature of the obtained isotherms of methanyl yellow adsorption differs, which indicates the difference between the mechanisms of its adsorption by sorbents. This is due to the different composition of functional groups on the surface of the studied sorbents and their textural characteristics. The most promising sample for use in enterosorption for the removal of low molecular weight toxic substances is the carbon sorbent Zoocarb.

Efficient removal of fluoride from neutral wastewater by green synthesized Zr/calcium sulfate whiskers: An experimental and theoretical study

A convenient and effective method was developed to fabricate zirconium-based calcium sulfate whiskers (Zr-CSWs), an environmentally friendly adsorption material designed to clean excessive fluoride from wastewater. Zr-CSWs, which potentially provide high adsorption activity toward fluoride in wastewater, overcome an aggregation problem typical of Zr-based species that may block the pore structure of the supporting material and degenerate its treatment performance. The results indicate that Zr-CSWs show excellent equilibrium adsorption capacity compared to other Zr-based materials in practical water solutions with pH values of 6–7. The adsorption of fluoride on Zr-CSWs was further evaluated in accordance with the Langmuir equation and the pseudosecond-order model. Coexisting anions had a minor effect on the removal of fluoride, and a strong alkali solution regenerated the used adsorbent. Density functional theory (DFT) calculations were performed to determine the mechanism of fluoride removal. The calculations demonstrated that the removal of fluoride by Zr-CSWs was mainly achieved by ion exchange between fluoride ions and OH - on the surface of the adsorbent, where a protonation process created low-coordination Zr atoms. • Zirconium decorated calcium sulfate whisker (Zr-CSW) was prepared in a simple and low-cost way. • Zr-CSW has high capacity and good selectivity for the removal of fluoride in water. • The adsorption follows Langmuir model and pseudosecond-order dynamic equation. • The mechanism for fluoride removal has been revealed by density of functional theory (DFT).

Characteristics of diatomite-alginate-Fe3O4 composite as a phosphate adsorbent

Technological approaches to the use of diatomaceous earth as a raw material for the creation of composite adsorbents for wastewater treatment from phosphate ions are analysed. It is shown that the developed surface of diatomite can be used to create a granular adsorbent, and iron (III) oxides (magnetite, goethite, lepidocrocite, ferrihydrite, hematite and goethite) are environmentally safe, cheap, economically feasible modifiers. Emphasis is placed on the possibility of obtaining magnetic granules due to the formation of magnetite. The use of the deposition method for the formation of the applied granular adsorbent is proposed.
 The influence of diatomite concentration on the static strength of granules was established. It is determined that the diameter of the nozzle is also an important factor. The selected technical solutions are aimed at solving the problems of granule hardening and ensuring high adsorption activity. Experimental studies of the synthesis and granulation of the composite adsorbent alginate - diatomaceous earth - magnetite have shown that an increase in the content of diatomaceous earth leads to a natural increase in the size of the granules. When increasing the diameter of the nozzle from 1.5 mm to 3.5 mm, for example, the size of the granules 1.5-4.0 (dc = 1.5 mm), 2.0-5.0 mm (dc = 3.0 mm) and 2.5-5.0 mm (dc = 3.5 mm). The diatomaceous earth content of more than 20% does not allow to carry out high-quality granulation on the experimental installation due to the increase in the viscosity of the suspension. The relationship between the size of gel granules and dried. The process of application of the active magnetic phase of the adsorbent is investigated. The dependence of the quality of the granulation process on the solid phase content is established. The measured static strength of the adsorbent granules is in the range of 17 - 25 kPa. It is established that the composite adsorbent with the applied layer of magnetite has magnetic properties. The adsorption of PO43- anions from aqueous solutions was studied. For the adsorbent alginate - diatomite and alginate - diatomite - Fe3O4 - the adsorption capacity is 4 and 9 mg PO43- / g, respectively. The obtained composite adsorbents have a set of functional properties that are promising for use in modern water purification and purification systems.

Microwave-assisted solvothermal synthesis of defective zirconium-organic framework as a recyclable nano-adsorbent with superior adsorption capacity for efficient removal of toxic organic dyes

Herein, the Zr-based metal–organic framework nanomaterial was successfully and rapidly synthesized by microwave method to serve as a new recyclable adsorbent. According to the material characterization, Zr-NDC with a particle size of 100 nm was a highly defective framework due to the missing linkers during the synthesis. The MOF showed excellent efficiency with low cost for adsorption of organic dyes, methylene blue and methyl orange, because of its superior maximum capacity (746 and 726 mg g−1, respectively) and reusability over several cycles of the adsorption. From results of adsorption studies, the high adsorption activity of Zr-NDC can be attributed to the defect sites in the framework and its physisorption character towards the dyes.

Highly efficient visible-light-driven photocatalytic degradation of organic pollutants by using magnetically separable supported heterogeneous nanocomposites (SiO2/Fe3O4/Ag2WO4)

In this work, the heterogeneous photocatalyst (SiO2/Fe3O4/Ag2WO4) that is composed of active nanomaterials precipitated onto mesoporous nanosilica was synthesized using multistep methods. The nanosilica was synthesized using the Stöber method. 10% Wt. of Fe3O4 and Ag2WO4 NPs were precipitated on the surface of nanosilica to produce supported SiO2/Fe3O4/Ag2WO4 magnetic nanoparticles (MNPs). Different techniques were used to characterize the synthesized supported MNPs, including UV-DRS, XRD, VSM, BET, BJH, and FE-SEM. The photocatalytic degradation activity of synthesized supported MNPs was conducted through a batch reactor towards methylene blue dye (M.B) under visible light irradiation (40 W LED and 55 W Xenon lamps). The experimental results showed a high degradation efficiency (approximately 100%) related to SiO2/Fe3O4/Ag2WO4 after 45 min of irradiation time. The SiO2/Fe3O4/Ag2WO4 revealed high adsorption activity, where 60% of its removal efficiency was during the first 60 min of adsorption in the dark. The kinetics studies revealed that the photocatalytic activity of SiO2/Fe3O4/Ag2WO4 was nearly 4.2 and 3.9 times higher than pure Ag2WO4 and SiO2/Fe3O4, respectively. The significantly improved photocatalytic activity of the SiO2/Fe3O4/Ag2WO4 MNPs was attributed to their higher stability and specific surface area, in addition to a synergistic outcome between Ag2WO4 and SiO2/Fe3O4 that leads to efficient electron–hole pairs separation. The effects of several parameters were also examined for supported MNPs, including catalyst dose, initial concentration of M.B, pH, and H2O2 addition. The reusability and recyclability study revealed that the synthesized SiO2/Fe3O4/Ag2WO4 are highly stable and can be used with high feasibility for removal of different organic dyes from wastewater.

Fabrication of porous octahedron-flowerlike microsphere NH2-UiO-66/CdIn2S4 heterojunction photocatalyst for enhanced photocatalytic CO2 reduction

Solar-driven carbon dioxide (CO2) photoreduction has been considered as an environmentally friendly and promising strategy to utilize solar energy and mitigate the impact of greenhouse effect. Designing novel cost-effective photocatalytic system with high CO2 molecules adsorption activity is an efficient avenue to enhance CO2 photoreduction performance. Herein, a series of NH2-UiO-66/CdIn2S4 (NU66/CIS) photocatalysts with different NU66 contents were constructed via facile in-situ hydrothermal route and displayed graceful morphology. According to a series of characterization results, porous octahedron NU66 were deeply anchored on flowerlike 3D-microspheres CIS, and a part of the small-sized CIS were evenly dispersed on the surface of NU66. Without any sacrificial agent, the optimized 8% NU66/CIS heterojunctions still exhibited the satisfactory photocatalytic efficiency for CO2 conversion, whose CO and CH4 yields reached up to 11.24 μ mol g−1 h−1 and 2.92 μ mol g−1 h−1, respectively, which were 2.87 and 3.31 folds higher than that of pristine CIS. The remarkably boosted activity of NU66/CIS was originated from the high specific surface area and the formation of heterostructure between the well-dispersed NU66 and CIS, which could promote the electron transfer during CO2 photocatalytic reduction.

Effects of acidity on the formation and adsorption activity of tungsten oxide nanostructures prepared via the acid precipitation method

This study systematically investigated the effects of the acidity of precursor suspension on the formation, physical properties, and adsorption activity of tungsten oxide nanostructures prepared via the acid precipitation method at room temperature. In highly acidic suspension (−0.85 ≤ pH ≤ −0.34), nanoplate orthorhombic tungsten oxide dihydrates (WO3·H2O) with a high crystallinity but with low adsorptive activity were formed. In moderate acidic suspension (0.04 ≤ pH ≤ 0.97), a novel hexagonal tungsten oxide, H-WO3, formed with a mixed morphology and a low crystallinity but with a high adsorptive activity. The effect of acidity was due to the vital role of high H+ ion concentration platform that acted as a scaffold for long-order arrangement and a breaker for confining the nanostructure of tungsten oxide. H-WO3 samples exhibited a high adsorption capacity (~30 mg/g) and a short adsorption–desorption equilibrium time (~15 min) with methylene blue. The adsorption kinetics of the samples followed the pseudo-second-order model, whereas their adsorption isotherm followed the monomolecular adsorptive Langmuir model. This study provides a simple energy-saving method for controlling the crystal structure and morphology of tungsten oxide nanostructures.

Modified graphene oxide composite aerogels for enhanced adsorption behavior to heavy metal ions

Exploiting adsorbents with high adsorption activity, good durability and low cost is still the core focus of water pollution treatment. In this study, sodium alginate (SA), graphene oxide (GO), and β-cyclodextrin (βCD) were used as raw materials to frame a composite aerogel with an orderly 3D network structure by a sol-gel and freeze-drying method. The incorporation of (graphene oxide)-β-cyclodextrin (GO-βCD) could make SA molecules have higher cohesion and create more active sites for adsorbates. The temperate ratio of GO-βCD and SA to be integrated was also discussed in this work. When GO-βCD was 4 wt% (i.e., SA/GO-βCD-4), the compress performance of the composite aerogel could be 37.97% higher than the original pure SA aerogel, and the saturated adsorption capacity for Cu2+ and Cd2+ reached up 148.49 and 174.85 mg/g. It shows that SA/GO-βCD-4 composite aerogels have excellent adsorption properties for metal ions. The test data was fitted to reveal the adsorption mechanism. The adsorption kinetics of the pseudo-second-order kinetic model and Langmuir isotherm models were identified to coincide with the adsorption behavior of the modified aerogel. Comprehensively, the synthesis of the samples could pave a new way for versatile adsorbents.

Adsorption performance of the polystyrene/montmorillonite composites: Effect of plasma treatment

Polystyrene/montmorillonite (PS/MMT) composite films with high adsorption activity were prepared via solution intercalation technique followed by treatment of composite films in low-pressure air plasma. Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and scanning electron microscopy were used to investigate the impact of plasma on the elemental composition and morphology of the composite surface. It was revealed that plasma treatment of the PS/MMT composite led to an increase in wettability and adsorption performance. The removal kinetics of methylene blue dye from aqueous solutions was experimentally studied. It was determined that plasma processing of the composite resulted in a significant improvement of the MB adsorption process: the initial rate of the process increased by 4 times (from 1.2 × 10−8 to 4.8 × 10−8 mol/(g•min)). Adsorption kinetic curves are obeyed the pseudo-second order reaction equation.

Features of adsorption human Ig on the surface of magnetically sensitive nanocomposites

Nanoscale magnetite (Fe3O4) and nanocomposite based on it (Fe3O4/SiO2) were synthesized. In the model physiological solution [0.9% NaCl solution (NSS)], the acid–base properties of the surface were potentiometrically investigated. Also the size and morphology transmission electron microscopy, surface (FTIR spectroscopy) and magnetic properties vibration magnetometer, specific surface area were investigated for the synthesized samples. The adsorption processes were studied and the high-adsorption activity of the Fe3O4 nanoparticles (MNPs) surface with respect to Ig was established in the model physiological environment and phosphate buffer at pH 6.86 [maximum adsorption capacity (Amax) 24.54 mg/g]. The analysis of kinetic dependences and Ig adsorption isotherms using mathematical models that take into account the chemical interaction in the system indicates the monomolecular nature of adsorption (Langmuir and Freundlich models). Due to their high biocompatibility, the obtained MNPs with immobilized Ig can be potentially suitable as adsorption materials for the creation of biosensors and targeted drug delivery.

Construction of MoS2 nanoarrays and MoO3 nanobelts: Two efficient adsorbents for removal of Pb(II), Au(III) and Methylene Blue

Toxic heavy metal ions, valuable noble metal ions and organic dyes are significant concerns in wastewater treatment. In this work, MoO3 nanobelts (MoO3 NBs) prepared by solvothermal method and MoS2 nanoarrays (MoS2 NAs) constructed using MoO3 NBs precursor were proposed to effectively remove heavy/noble metal ions and organic dyes, such as Pb(II), Au(III) and Methylene Blue (MB). The two adsorbents exhibited the excellent adsorption capacity towards Pb(II), Au(III) and MB. The maximum removal capacity of Pb(II) and MB on MoO3 NBs was 684.93 mg/g and 1408 mg/g, respectively, whereas that of Au(III) and MB on MoS2 NAs was 1280.2 mg/g and 768 mg/g, respectively. Furthermore, the thermodynamic parameters were calculated from the temperature-dependent curves, suggesting that the removal of Pb(II) and Au(III) on both adsorbents was spontaneous and endothermic. The new adsorbents introduced here were high adsorption activity, ease of fabrication, high scalability, good chemical stability, great repeatability and abundant and cheap supply, which were highly attractive for wastewater treatment.

Nano-Bioremediation of Municipal Wastewater Using Myco-Synthesized Iron Nanoparticles

Metal nanostructures have potential effective impacts with many arenas like catalysis, sensors, optics, electronics, functional materials, environment and medicine. Thus, iron nanoparticles (FeNPs) were mycogenic synthesized in this study as effective antimicrobial agent and heavy metals removers. The isolation of 37 fungi were done from contaminated 10 soil (with iron ions or metals) samples and they screened. The most powerful fungal isolate was Fusarium oxysporum. Biosynthesized FeNPs size were 0.7 to 3 nm (high small size) with spherical shape based on TEM analysis. However, XRD, FT-IR analyses confirmed that characterization and led to form iron at zero valent. The obtained FeNPs were used as antibacterial agent against broad spectrum of environmental pathogens with minimum amounts (about 20 µg/ml) compared with reference antibiotics. This drive for using it to control microbial pathogens through municipal wastewater. For its high adsorption activity, it is used for removing heavy metals from their contaminated wastewater.

Hydrodeoxygenation of guiacol over ion-exchanged ruthenium ZSM-5 and BEA zeolites

Ion exchanged Ru/ZSM-5 and Ru/BEA catalysts, prepared by replacing the extra framework NH4+ cations in zeolites with Ru3+ ions, are employed for the hydrodeoxygenation of guaiacol. The performance results indicate ion-exchanged Ru zeolites, with extremely low Ru contents (~0.2 wt%), possess a high intrinsic HDO activity compared to the catalysts prepared by the incipient wetness impregnation method. On the basis of TEM, FTIR, XPS and TPD analysis, the NH4+ ions in zeolite were substituted by Ru species, with metal particles entered the zeolite cages and finely dispersed on the support. These ion-exchanged Ru particles exhibit a strong electronic interaction with oxygen atoms of zeolite framework with a mixed Ru(0)-Ru(III) species observed in the reduced samples. In contrast, only Ru0 was detected in the reduced impregnated Ru/ZSM-5. The partial-reduced Ru species over the ion-exchanged Ru/ZSM-5 catalyst shows a high H2 adsorption activity facilitating the hydrogenation of guaiacol to the saturated products (such as 2-methoxycyclohexanol). In addition, ion-exchanged Ru-ZSM-5 and Ru-BEA catalysts present a similar normalized cyclohexane formation rate (based on the concentration of acid sites), suggesting the acid sites play a pivotal role in the deoxygenation of 2-methoxycyclohexanol to cyclohexane.

Preparation of a hybrids APT@MIL by one-step solvent-thermal method for effectively degrading organics.

The attapulgite (APT), a typical nano-rod structured clay was introduced to MIL-101(Fe), a typical eco-friendly iron-based Metal-Organic Framework material (MOF), during the preparation by a one-step solvothermal method, which afforded a novel APT and MOF hybrid (APT@MIL). Based on the characterization of SEM, FT-IR and XRD, it was found that the rod-like crystals of APT determined the size of MIL-101(Fe) while maintaining its regular octahedral crystal form, and the crystal size of MIL-101(Fe) in APT@MIL enlarged 4 times. It was also discovered that the rod-like APT were evenly distributed in MIL-101(Fe) crystals. Using APT@MIL as the photocatalyst, some organic dyes were photodegraded in simulated sunlight. The analysis indicated that APT@MIL has high adsorption and photodegradation activity, the removal rate of methylene blue was up to 99.5%. Finally, the photocatalytic activity of APT@MIL was verified by UV-Vis DRS, photoluminescence spectra. The thermodynamic adsorption, kinetic characteristics adsorption, and removal mechanism of APT@MIL are also discussed. In summary, a novel hybrid material APT@MIL was successfully prepared with good adsorption and photocatalytic performance. It is expected to be used in photocatalytic degradation of dye wastewater.

MIL-101(Fe) nanodot-induced improvement of adsorption and photocatalytic activity of carbon fiber/TiO2-based weavable photocatalyst for removing pharmaceutical pollutants

Abstract The decoration of TiO2-based junctions on carbon fibers (CFs) has been well-developed as weavable photocatalysts for degrading hazardous pharmaceutical pollutants, but their practical application is still constrained by unsatisfactory adsorption and photodegradation performances, resulting from low surface area/porosity and photoactivity. Herein, we propose the growth of MIL-101(Fe) nanodots with small size of 5–10 nm as a porous co-photocatalyst to decorate TiO2 nanorods on CFs. CFs/TiO2/MIL-101(Fe) bundles display a wide absorption with an edge (∼600 nm). Subsequently, CFs/TiO2/MIL-101(Fe) bundles are weaved into a macroscopical cloth (0.2 g, 4 × 4 cm2). CFs/TiO2/MIL-101(Fe) cloth can efficiently adsorb 46.9% 17β-estradiol (E2) and 40.2% tetracycline hydrochloride (TC) after 60 min in the dark, with obvious improvement (5.4–8.4 times) compared with that by CFs/TiO2 cloth (8.7% E2 and 4.8% TC). Importantly, under visible light irradiation, CFs/TiO2/MIL-101(Fe) cloth can remove 87.4% E2 and 94.2% TC in 60 min, which is 6–13.1 times compared with that by CFs/TiO2 cloth (14.6% E2 and 7.2% TC), resulting from the high adsorption and three-component synergistic photocatalytic activity. Therefore, the construction of semiconductor-MOF nanojunctions on CFs provides a general strategy to develop novel weavable photocatalysts for eliminating pharmaceutical pollutants.
