The removal of heavy metal cations and co-existing anions represents one of the promising pathways to produce purified water for industry. Laminar MXene membrane has attracted tremendous research interest in the separation field in the past decade. The thermal self cross-linking MXene membrane has been proven to exhibit good anti-swelling performance. However, the decrease of negative charge during self-crosslinking leads to decreasing ion separation performance due to fading adsorption and/or weakened surface-charged controlling effect. To regenerate the surface charge, the hydroxylation of MXene membrane is adopted by substituting –F with –OH using the alkali of KOH. The resultant hydroxylated MXene membrane demonstrates overall better performance than the pristine MXene membrane in wettability and Zeta potential, promoting the rejection and separation of ions. When two selective membranes are applied to remove the heavy metal cations (Pb2+, Cu2+, and Cd2+) and co-existing anions (Cl− and/or NO3−) under the electronic field with appropriate voltage, the rejection of 99.5% can be obtained at 12 V for a 383 nm-thick hydroxylated MXene membrane, higher than that of pristine MXene membrane. As a result, the co-existing anions were also excluded at ~97% via increasing surface-charged controlling effect. Moreover, the hydroxylated MXene membrane also shows selective separation permeance on Na+/Pb2+, Na+/Cu2+, and Na+/Cd2+ pairs. By controlling the interlayer spacing through thermal self-linking route, good operational durability and reproducibility are also achieved for the hydroxylated MXene membrane during the 70-min test. These highlight the potential of developing and applying 2D laminar membrane for separation and treatment of wastewater.

Benzaldehyde (BzH) is an important chemical for industrial feedstock. However, the conventional production processes heavily rely on precious metal catalysts and bring about unavoidable pollution issues. Here we report a new catalytic process to use N-doped graphene oxide (NGO) as the catalyst for oxidation of benzyl alcohol (BzOH) into BzH by an environmentally benign oxidant, peroxymonosulfate (PMS). Different approaches are developed to synthesize carbonylated NGO, which shows higher catalytic efficiency than CO-deficient NGO. The optimized catalyst could achieve 96% BzOH conversion and unprecedented 82% BzH yield under mild temperature (50 °C), superior to some precious metal catalysts reported. Experimental studies unveil the indispensable roles of pyridinic N and ketonic CO groups in forming an electron bridge between BzOH and PMS for non-radical oxidation, or separately inducing radical oxidation. The non-radical oxidation process is more selective in yielding BzH. Furthermore, the yielded BzH is free from over-oxidation into benzoic acid under various reaction conditions, because the radicals preferentially react with BzOH other than BzH and the BzH can hardly adsorb on graphene sheets, thus inhibiting its further oxidation. This work provides a cheap material and mechanic understanding of carbocatalysis for green organic synthesis with environmental and economic perspectives.

An iron-nitrogen-boron-carbon (Fe–N–B–C) bifunctional electrocatalyst was prepared by means of a facile one-step hydrothermal reduction of graphene oxide using dimethylamine borane as doping agent. In addition, hemins were efficiently anchored during doping/reducing process on this modified graphene. The as-prepared Fe–N–B–C electro-catalyst showed enhanced response as regards its potential for reduction of H2O2 and O2. In view of its catalytic activity, this Fe–N–B–C material was tested for the determination of H2O2 with a chronoamperometry method, obtaining a detection limit as low as 0.055 μM, which is better than that of some Hemin-N-C materials. Regarding O2 reduction reaction, a study performed using a rotating disk electrode indicated that this material exhibits a positive onset potential (0.90V vs. RHE), high selectivity (4e− process), high limiting-current density (4.75 mA cm−2) and strong resistance against the crossover-effect from methanol in alkaline medium, making it to be the promising candidate as alternative for commercial Pt/C catalysts. These results could have commercial and environmental relevance and would deserve further complementary investigation.

The development of aqueous sodium-ion batteries (ASIBs) has been greatly restricted as a result of their narrow electrochemical stability window (ESW) (about 1.23 V). Many researchers attempt to expand the ESW using high concentrations of electrolyte solution or choosing titanium or other inert materials as collectors. However, these methods would lead to higher battery costs. In this work, we demonstrated a low-cost ASIB system, in which the cathode, anode, and electrolyte solution were applied by graphene oxide (GO)-modified Na2MnFe(CN)6 (PBM), zinc sheet, and solution of Na2SO4 (1 M) and ZnSO4 (1 M), respectively. When the graphite sheet with high hydrogen and oxygen evolution overpotential was used as the collector, the ESW was expanded to about 3.4 V. The full cell owned a stable discharge platform and high discharge potential (∼1.8 V). Furthermore, the modification of PBM by reduced graphene oxide (rGO) obviously increased the discharge capacity to 110 mAh g–1, extended the cycle life (91% capacity retention after 200 cycles), and greatly improved the rate capacity (76% capacity for 500 mA g–1 rate). It should also be noted that the full cell consisting of a rGO/PBM cathode and zinc anode could achieve an energy density as high as 165 Wh kg–1.

Meeting the escalating demand for clean water resources is one of the key challenges to ensure a sustainable future. Catalysis plays an important role to advance the chemical reactions required for wastewater efficient remediation. How to exploit high‐performance catalysts to boost the pivotal reaction kinetics always attracts researchers’ enthusiasm. Perovskite oxides as a novel class of functional materials can be tuned to confer compositional flexibilities and provide rich and unique structural properties. As the rising‐star material, it has been widely probed for electrocatalysis, photocatalysis, and membrane‐catalysis for energy conversion, but received less attention in water treatment. In this review, the advances of perovskite oxides for advanced oxidation processes (AOPs) in water remediation are comprehensively elaborated. A fundamental understanding of the crystal structures and properties of perovskite oxides as well as the basic principles of AOPs is firstly provided. Then, emphasis is placed on how to tune the perovskite oxides to suit various AOPs. The strategies to design novel perovskite oxides to enhance the catalytic activities in AOPs have been highlighted. It is expected that after reading this review, readers will have a clearer vision of the background, the state of the art development, and general guidelines for future directions regarding research in this area.

Global bacterial infections associated with conventional polyvinyl chloride (PVC) medical devices place a heavy burden on healthcare systems and thus it will be desirable if medical devices are made from antimicrobial PVC. There are numerous studies focusing on polymer surface modifications to either leach antimicrobial agents or kill pathogenic microbes upon direct contact. In this work, mannitol fumarate ester‐based aluminum metal alkoxide (MFE‐Al) additive was developed to confer simultaneously improved antibacterial property and enhanced high temperature sterilization resistance of the resultant PVC. Data obtained confirm that the MFE‐Al stabilized PVC sheets significantly inhibit 98% bacterial growth. They also show biocompatibility with cultured H9C2 cardiomyocytes and hemocompatibility in vitro. Dry heat sterilization is generally not suitable for PVC medical wares due to their poor thermal compatibility. Surprisingly, our antimicrobial‐biocompatible PVC can maintain stability at 180°C for 90 min. Such a high thermal stability indicates the MFE‐Al stabilized PVC can endure 90 cycles of dry‐heat sterilization without significant damage. This study may provide a solution to reduce PVC medical waste for a maximum benefit without compromising human health or the environment.

Summary Ruddlesden-Popper perovskite oxide (An+1BnO3n+1) mixed ionic-electronic conducting membranes are proposed as a new method for oxygen separation from air. Element doping was used to improve the ionic conductivity and to stabilize the crystal structure. The doping of orthorhombic Pr2NiO4 with Mo resulted in the ex situ collapse of the crystal together with the generation of impurities by the rearrangement of Pr atoms. Mo doping also inhibited the in situ phase transition from low-order Pr2NiO4 to high-order Pr4Ni3O10 by weakening the covalent interaction between Pr and O. Membranes made from Pr2Ni0.95Mo0.05O4+δ showed an oxygen flux of 3.35 mL min−1 cm−2 at 1,000°C, high permeation stability in air and helium, and high CO2 tolerance with no decline of oxygen flux during 500 h at 900°C. This work advances a comprehensive understanding of phase transitions on Pr2Ni1−xMoxO4 and provides an effective way to improve the oxygen permeability via in situ stabilization of the phase structure.

Metal organic frameworks (MOFs) are frequently used as adsorbents in adsorption processes to remove dyes from effluent produced by the textile industry. Today, dye contaminants have become an important environmental problem. One of these dyes is methylene blue (MB) and its removal from wastewater is a priority because it is persistent and nondegradable. MB is used in many industries although it has potential harmful effects on human and aquatic life and can be considered a hazardous chemical when in wastewater. The present study shows the potential applications for enhanced forms of UiO-66 MOFs, such as UiO-66, UiO-66-10%Al and UiO-66-30%Al. These forms were prepared to remove MB from wastewater using batch experiments. Characterisation of adsorbents were accomplished successfully using Fourier transform infrared, X-ray powder diffraction, Brunauer–Emmett–Teller surface area and thermogravimetric analysis techniques. To investigate equilibrium adsorptive behaviour, Langmuir and Freundlich isotherm models were tested against the experimental data. Based on linear regression correlation coefficient (R2), the Freundlich model described the equilibrium isotherm of MOF/MB better than the Langmuir model. Of all forms of UiO-66 MOF, UiO-66-10%Al had the maximum Langmuir adsorption capacity at 49.26 mg/g. A kinetics study examined pseudo first-order, pseudo second order and Elovich models to determine which could explain the sorption mechanism. While the pseudo second order and Elovich models showed a good fit with the experimental data, the correlation coefficient of the pseudo second-order model was the highest. These results indicate that adsorption of MB is controlled by a chemisorption mechanism. Further, intraparticle diffusion was utilised to describe the adsorption mechanism and determine the rate-limiting steps in the adsorption process.

The development of novel single atom catalyst (SAC) is highly desirable in organic synthesis to achieve the maximized atomic efficiency. Here, a Co‐based SAC on nitrogen‐doped graphene ([email protected]) with high Co content of 4.1 wt% is reported. Various characterization results suggest that the monodispersed Co atoms are coordinated with N atoms to form robust and highly effective catalytic centers to activate peroxymonosulfate (PMS) for organic selective oxidation. The catalytic performance of the [email protected]/PMS system is conducted on the selective oxidation of benzyl alcohol (BzOH) showing high efficiency with over 90% conversion and benzaldehyde selectivity within 180 min under mild conditions. Both radical and non‐radical processes occurred in the selective oxidation of BzOH, but the non‐radical oxidation plays the dominant role which is accomplished by the adsorption of BzOH/PMS on the surface of [email protected] and the subsequent electron transfer through the carbon matrix. This work provides new insights to the preparation of efficient transition metal‐based single atom catalysts and their potential applications in PMS mediated selective oxidation of alcohols.

Direct production of higher alcohols from syngas provides a promising route for the conversion of methane-rich feedstocks into value-added commodity chemicals. However, the rational catalyst design for this process remains a challenge due to severe long-standing sintering problem, low dispersion of active sites and uncontrollable synergism between CO dissociation and CO insertion. Here, we demonstrate the successful development of highly active catalyst for higher alcohols production based on the confined carbonization in metal-organic framework (MOF) matrix. Starting from a compound consisting of cobalt-based MOF host (ZIF-67) and molybdenum-based polyoxometalates guest (H3PMo12O40), Co/Co6Mo6C confined in the carbon matrix is achieved with well-defined morphology and high porosity after carbonation in N2. The Co4.7[email protected] with optimal fraction of Co0 and Co6Mo6C exhibits remarkable performance for higher alcohols synthesis, with a CO conversion of 48% and C2+OH space time yield of 99 mg/gcat.h under 275 °C and 3.0 MPa. Compared to the literature, the developed Co4.7[email protected] catalyst from MOF displayed favourable higher alcohols production rates. The balance of Co0/Co6Mo6C is found to be crucial for the observed reactivity, where Co0 is for CO dissociation and C-C chain growth and Co6Mo6C is highly efficient for CO nondissociative adsorption and CO insertion. Moreover, the synthesized catalyst also displays exceptional stability in a 100 h long-term stability test owing to the uniform dispersion of active centres, demonstrating great potential for large-scale application.

Oxygen permeable ceramic hollow fiber perovskite membranes could be applied as the micro-membrane reactors for high temperature oxidations to integrate air separation and reaction in same unit. Membrane reactors normally require the loading of extra catalyst. However, how to anchor the catalysts in these hollow fiber structured reactors along the surface is a big issue. In this work, the synthesis and properties of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) hollow fiber perovskite membranes with wrinkled surface was reported. This article demonstrates its applicability for oxygen separation from air, before and after Ag deposition as the catalyst in the wrinkles of the hollow fibers. The wrinkled membranes display the oxygen permeation flux of 0.62 (prior to Ag deposition) and 1.48 (after Ag loading) mL·min−1·cm−2 operated at 950 °C, which is 1.2 and 3.0 times the permeation flux of membranes without wrinkles, respectively. This research contributes a novel inorganic hollow fiber membrane with wrinkled surfaces as the catalyst bed for industrial applications.

Hydrogen fuel has been embraced as a potential long-term solution to the growing demand for clean energy. A membrane-assisted separation is promising in producing high-purity H2. Molecular sieving membranes (MSMs) are endowed with high gas selectivity and permeability because their well-defined micropores can facilitate molecular exclusion, diffusion, and adsorption. In this work, MXene nanosheets intercalated with Ni2+ were assembled to form an MSM supported on Al2O3 hollow fiber via a vacuum-assisted filtration and drying process. The prepared membranes showed excellent H2/CO2 mixture separation performance at room temperature. Separation factor reached 615 with a hydrogen permeance of 8.35 × 10−8 mol·m−2×s−1×Pa−1. Compared with the original Ti3C2Tx/Al2O3 hollow fiber membranes, the permeation of hydrogen through the Ni2+-Ti3C2Tx/Al2O3 membrane was considerably increased, stemming from the strong interaction between the negatively charged MXene nanosheets and Ni2+. The interlayer spacing of MSMs was tuned by Ni2+. During 200-hour testing, the resultant membrane maintained an excellent gas separation without any substantial performance decline. Our results indicate that the Ni2+ tailored Ti3C2Tx/Al2O3 hollow fiber membranes can inspire promising industrial applications.

The metallic nickel hollow fiber membranes (NHFMs) consisting of a dense skin layer integrated on porous nickel substrate were fabricated in a single extrusion step by using a 90 wt% NMP-H2O solution and water as the respective internal and external coagulants during the spinning process. The resultant asymmetric Ni hollow fibers by sintering were directly applied to hydrogen production from methane steam reforming (MSR), where the porous internal surface functioned as a catalyst bed for MSR reactions, and the external dense skin layer served as the membrane for hydrogen extraction from the reaction products. The effects of the feed composition in terms of steam-to-methane ratio (H2O/CH4) and methane concentration; the operational parameters including temperature, space velocity, and the sweep gas flow rate on the performance of the hollow fibers were investigated. The results reveal that the reaction operational temperature should be above 800 °C and the H2O/CH4 ratio controlled around 3 so as to achieve both high methane conversion and high H2 production rate. When operated at 1000 °C and 25,937 h−1 methane space velocity, the maximum H2 production rate reached 50.84 mmol m−2 s−1 while the methane conversion reached at 98.58%. In order to produce pure hydrogen, steam may be used as the sweep fluid instead of inert gases such as nitrogen to prevent the dilution of the permeated gaseous hydrogen. The prepared asymmetric NHFMs also demonstrate high chemical stability in the reformate gases and high resistance to carbon deposition at above 800 °C, and thus may be a promising way of cost-effective hydrogen production by MSR at high temperatures.

Photocatalytic hydrogen evolution reaction (PER) suffers from deficient solar light efficiency, high cost of noble-metal cocatalysts and low responses to visible and infrared light. In this article, we report single-atom silver incorporated g-C3N4 (SAAg-g-CN) as a low-cost and stable catalyst with higher activities in PER and solar-heat-assisted PER processes than Ag nanoparticle decorated g-C3N4 (AgNP-g-CN) and PtNP-g-C3N4. The excellent activity of SAAg-g-CN is benefited from the proper Gibbs free energy of the adsorbed hydrogen atom (ΔGH*) and robust structure of N-Ag bonding of the SAAg-g-CN. The PER rate of SAAg-g-CN at 55 °C was doubled as compared to that at 25 °C, meanwhile, AgNP-g-CN and PtNP-g-CN showed descending PER performances, due to the agglomeration of metal NPs. This work demonstrates the ultrahigh photoactivity and photothermal stability of SAAg-g-CN, and its potential in facilitating the full exploitation of solar energy.

In this study, three improved versions of UiO-66 metal organic frameworks (MOFs) were synthesised successfully: Different ratios of Ca+2/Zr+4 were used to synthesise UiO-66, UiO-66-10%Ca and UiO-66-30%Ca. Batch adsorption experiments were achieved to remove MB from wastewater by UiO-66-Ca. UiO-66-10%Ca exhibited the highest adsorption capacity with maximum MB adsorption capacity of 15 mg. g–1 in UiO-66-30%Ca while UiO-66 demonstrated lower MB loading. Langmuir and Freundlich models have been employed to describe isotherms. A kinetics study indicated pseudo first-order and pseudo second-order equations. In addition, an intraparticle diffusion model was utilised. The results presented here may facilitate the further enhancement of UiO-66 MOFs and advance the synthesis of multimetal MOFs in future research.
