Summary: Efficient spatial charge separation is crucial for improving photocatalytic performance. In this study, 1T/2H MS/BOC and 2H MS/BOC piezo-photocatalysts were synthesized. The combination of piezoelectric catalysis and photocatalysis led to a highly active piezo-photocatalytic process. The optimized 1T/2H MS/BOC catalyst showed superior DCF degradation and H-2 evolution activity under ultrasound and light. The improvement in performance can be attributed to the polarization electric field, abundance of active sites, and advantageous band structure between BiOCl and 1T/2H MoSe2.

Summary: This study prepared Co3O4 nanoplates with a uniform nanostructure through the thermolysis of cobalt hydroxide at different temperatures, and reported for the first time the influence of annealing temperature on their mimetic enzyme activity. The results showed that Co3O4 nanoplates annealed at 200 degrees C exhibited strong oxidase activity and efficiently catalyzed the oxidation of TMB without the addition of hydrogen peroxide. However, the oxidase activity of Co3O4 decreased rapidly and even became inactive when the annealing temperature was increased to 500 degrees C and 800 degrees C.

Summary: In this study, multifunctional composite photocatalysts were fabricated by coupling sea urchin shaped ZnO with MoS2 and PANI sheets, showing a significant improvement in photocatalytic activity compared to pristine components. The ternary ZnO-MoS2-PANI photocatalyst exhibited excellent adsorptive decomposition of organic pollutants under natural sunlight irradiation, and enhanced photocatalytic hydrogen evolution. The presence of MoS2 in the composite provided abundant catalytic active sites for pollutant adsorption, while the higher loading of MoS2 in the composite decreased photocatalytic activity for hydrogen evolution. These results may guide the design and development of ZnO based multifunctional materials for diverse photocatalytic applications.

Summary: This work investigates the photocatalytic performance of ternary CuO-Ag-ZnO nanowires synthesized using a two-step approach. The introduction of Ag and CuO nanostructures onto the surface of ZnO nanowires is achieved through plasma electrolytic oxidation. The as-prepared samples are characterized in terms of structure, size, morphology, and optical properties. The CuO-Ag-ZnO nanowires exhibit higher decolorization rate and shorter half-life time compared to Ag-ZnO and bare ZnO nanowires, indicating superior visible light-driven photocatalytic properties. The synergic incorporation between noble metal-semiconductor or semiconductor-semiconductor at the interfaces of Ag-CuO, Ag-ZnO, and CuO-ZnO expands the visible light absorption range and eliminates photogenerated electron-hole recombination.

Summary: Growing pollution and high energy demand are major challenges for humans. Water pollution caused by industrial waste and irresponsible human activities is a significant problem. Photocatalysis, utilizing solar light as an energy source, is emerging as an efficient alternative for energy and water purification. However, photocatalysts face limitations such as photocarriers recombination, low surface area, and limited light absorption. Modifications like defect modifications and heterojunctions can be employed to overcome these limitations. Among them, the Z-scheme heterojunctions are an effective way to improve the performance of photocatalysts. To further enhance their activity, a dual Z-scheme photocatalytic scheme has been developed. This review discusses different types of dual Z-schemes and their applications in water purification, as well as future research prospects.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
