Summary: In this study, MXene was used as the precursor to prepare hetero-structured TiO2/TiS2 by the hydrothermal method. The rough particles provided a channel for the rapid transport of sodium ions and relieved the stacking state of nanosheets. The maximum desalination capacity of the TiO2/TiS2 electrode was 36.45 mg g(-1) (NaCl), with a capacity retention rate of about 75% after 30 cycles. This study shows that TiO2/TiS2 obtained from MXene offers a new idea to solve the problem of poor electrochemical properties of TiO2.

Summary: Constructing heterostructures is an effective strategy for efficient photocatalysis, and the type of heterojunctions is determined by the charge carrier transfer path. Understanding the charge carrier transfer mechanism of heterojunctions is crucial for guiding the construction of rational heterojunctions. In this study, an S-scheme K6Nb10.8O30@Zn2In2S5 (KNbO@ZIS) heterojunction with a 1D/2D core-shell structure is designed to improve photocatalytic hydrogen production. The improved photocatalytic performance is mainly attributed to the suppressed charge carrier recombination and accelerated charge carrier transfer in the photocatalysts.

Summary: In this study, the effects of polystyrene microplastics on removing three tetracyclines using ferrate were examined. The presence of polystyrene microplastics influenced the oxidation, adsorption, coagulation, and complexation efficiency, resulting in varying degrees of tetracycline removal. Polystyrene microplastics weakened the oxidation capacity of ferrate but aided in tetracycline adsorption due to their increased surface area and pore volume. They also acted as support sites for Fe3+ and Fe(OH)(3), facilitating the formation of polystyrene-Fe-tetracycline complexes. The potential adverse effects of polystyrene microplastics in aquatic environments require more attention in removing pollutants.

Summary: The complexation of tetracyclines with Fe species plays a significant role in the removal of tetracyclines by ferrate. Experimental results show that the complexation of tetracyclines with Fe3+ contributes to 79% of the overall removal, followed by oxidation (11%) and adsorption/flocculation (10%). Thermodynamic and kinetic calculations suggest that complexation reactions between Fe3+ and tetracyclines are more likely to occur than oxidation reactions between ferrate and hydroxyl radicals. The complexation rates of tetracyclines with Fe3+ determine the removal of multiple tetracyclines by ferrate, highlighting the importance of considering complexation in the removal of pollutants.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
