Summary: In this work, Na5V12O32 nanowires on Ti foil were prepared by a hydrothermal method, and then V2O5/ BiVO4 nanowires were fabricated by a controllable ion-exchange and calcination methods. The samples were characterized by various techniques. After the ion-exchange process, nanosheets were observed on the surface of the nanowires, which could be transformed into nanoparticles after calcination. The V2O5/BiVO4 nanowires exhibited higher photogenerated charge carrier separation efficiency and better photocatalytic degradation of methylene blue compared to BiVO4.

Summary: This research synthesized a hybrid of alpha-MoO3/ZnO heterostructures and evaluated its photocatalytic activity in degrading Methylene Blue dye (MB) under visible light. The addition of alpha-MoO3 changed the morphology of ZnO from hexagonal to rod-like nanorods. The hybrid (MZ-21) showed three times faster MB degradation rate compared to ZnO nanoparticle. The study also determined the optimal conditions for efficient MB degradation.

Summary: Here, Fe doped MoS2/BiVO4 magnetic heterostructure composites were synthesized using a sonication-assisted hydrothermal method. The synthesized composites were characterized for crystal structures, morphology, surficial chemical properties, photocatalysis, and antimicrobial properties. The Fe@MoS2/BiVO4 p-n heterojunction exhibited superior degradation of methylene blue dye in the visible light range. The incorporation of composite materials reduced the bandgap energy, facilitating more energy absorption in the visible light spectrum. The enhanced photocatalytic activity of Fe@MoS2/BiVO4 was attributed to a large carrier lifetime and the synergistic effect of the p-n heterojunction.
The antimicrobial investigation showed that 1 wt% Fe@MoS2/BiVO4 exhibited good antimicrobial response against Escherichia coli (E. coli). These findings provide insights into the photocatalytic mechanism, p-n junction formation mechanism, and possible antimicrobial mechanisms of Fe-doped MoS2/BiVO4.

Summary: In this study, graphitic carbon nitride (GCN) decorated manganese oxide (Mn2O3) materials with different concentrations of GCN were synthesized and used for photocatalytic degradation of methylene blue (MB) contaminant. It was found that 60% GCN decorated Mn2O3 showed excellent photocatalytic performance with over 99% capability for MB breakdown. The improved photocatalytic activity was attributed to good crystallinity, defined shape, superior optical band gap, and smaller particle size.

Summary: A step-scheme BiVO4/Ag3VO4 composite was synthesized for the degradation of methylene blue through a hydrothermal and chemical deposition process. The composite exhibited excellent photocatalytic degradation properties, outperforming BiVO4 and Ag3VO4, with enhanced stability. This improvement in catalytic performance was attributed to its novel step-scheme mechanism facilitating charge separation and increased lifetime.

Summary: This study synthesized six cocatalysts and deposited them on the surface of BiVO4 to improve the surface catalytic efficiency and photogenerated carries separation efficiency of BiVO4. The results showed that these catalysts can significantly enhance the photocatalytic water oxidation performance compared to pure BiVO4. Among them, the Co-Co PBA@BiVO4 catalyst was extensively characterized and found to capture more photons and improve the surface catalytic efficiency of BiVO4.

Summary: The crystal morphology of nanomaterials plays a significant role in their adsorption-photocatalytic activities. In this study, ZnS nanomaterials with different shapes were synthesized using ZnO as templates. It was found that short nanotubes exhibited excellent adsorption performance for methylene blue, while nanosheets showed the highest photocatalytic efficiency. Furthermore, the higher exposure ratio of {100} crystal planes on nanosheets not only resulted in a narrower bandgap but also provided more sites for adsorption and electron/hole trapping.
