Summary: The new Z-scheme TiO2/g-C3N4/Bi2WO6 ternary heterojunction synthesized through a simple hydrothermal method exhibits enhanced photocatalytic activities for organic pollutants under visible light irradiation. This enhancement is mainly attributed to the decrease in recombination of photo excited hole-electron pairs, enhancing the lifetime of photo induced charge carrier, and the combined action of active species promoting the photocatalytic process.

Summary: The study investigated the enhancement of photocatalytic activities by doping Mo ions into Bi2WO6, revealing that the optimal Mo doping concentration is 0.25% to achieve approximately 2-fold improvement in photocatalytic activity. The presence of Mo ions below the conduction band edge of Bi2WO6 acts as an electron trapping site to prevent electron transition, ultimately enhancing photocatalytic efficiency with superoxide anion radicals established as the main active species.

Summary: Exploiting non-noble metallic cocatalysts is important for photocatalytic H2 production. In this study, metallic 1T-rich MoS2 nanoparticles were embedded in C3N4 hollow spheres using an in-situ transformation method. The embedded hollow sphere structure enhances heterojunction interaction and the 1T-rich MoS2 cocatalyst promotes electron transfer and improves photogenerated carrier separation and transmission, leading to enhanced H2 production. The CN/MoS2-1 catalyst exhibits significantly improved H2 production rate (441.3 μmol g-1 h-1) and maintains outstanding stability, suggesting potential for future catalyst-cocatalyst system design to enhance photocatalytic H2 production.
