Summary: In this study, NiO/Zn3In2S6 p-n heterojunction photocatalysts were prepared using the ultrasonic assisted deposition method. The photocatalytic performance of the p-n photocatalysts for hydrogen evolution was evaluated and the effect of different mass ratios of NiO to ZIS(6) was explored. The results showed that the 25% NiO/ZIS(6) sample exhibited the best photocatalytic hydrogen evolution activity with a hydrogen evolution rate 7.65 times higher than that of ZIS(6). Mechanism exploration revealed that the formation of NiO/ZIS(6) p-n heterojunction effectively promoted the separation and migration of photoinduced electrons and holes, while inhibiting the recombination of charge carriers. This work is of great significance for the design and preparation of novel p-n heterojunction photocatalysts with efficient photocatalytic hydrogen evolution performance and high stability.

Summary: In this study, Ni2P nanoparticles-decorated g-C3N4 photocatalysts were prepared via liquid exfoliation of g-C3N4 followed by in-situ loading of Ni2P nanoparticles. The optimized Ni2P/g-C3N4 exhibits high performance in visible-light-driven hydrogen evolution, attributed to the robust interfacial structure and enhanced transfer of photoinduced electron.

Summary: In this study, a one-dimensional MnxCd1-xS@D-MoSeyS2-y heterostructure was prepared to improve the photocatalytic hydrogen generation efficiency by adjusting the molar ratio of Mn to Cd in the solid solution. The introduction of MoSeyS2-y as cocatalyst with defects during the photocatalytic process enhanced the activity of H2 evolution. The optimized structure exhibited improved photocatalytic performance with a hydrogen evolution rate 37 times higher than that of CdS.

Summary: In this study, selenium-enriched amorphous NiSe1+x nanoclusters were integrated with TiO2 to enhance the hydrogen-generation rate. Compared to crystalline nickel selenide, amorphous NiSe1+x exhibited more unsaturated active Se atoms, leading to higher hydrogen-production activity. The enriched Se-mediated mechanism was proposed to explain the boosted hydrogen-generation rate of aNiSe(1+x)/TiO2.

Summary: In this study, we demonstrate that a Rh/Zn(OH)(2) catalyst prepared by an in situ photodeposition strategy can significantly enhance water dissociation kinetics and improve the photocatalytic hydrogen evolution reaction (HER) in a mild alkaline environment. Multiple factors, including the strong interaction between Rh nanoparticles (NPs) and Zn(OH)(2) and the accelerated water dissociation kinetics, contribute to the excellent photocatalytic performance of the Rh/Zn(OH)(2) catalyst.

Summary: Researchers have synthesized cobalt porphyrin substituted myoglobin (CoMb) as a homogeneous catalyst for photo-driven CO2 to CO conversion in water. By optimizing the activity and product selectivity through varying pH and concentrations of the enzyme and the photosensitizer, they achieved high efficiency of CO generation. They further enhanced the CO2-reducing performance by introducing positively charged residues near the active site of CoMb.

Summary: The ZnCdS/NiAl LDH heterojunction catalyst shows highly effective photocatalytic hydrogen evolution activity, with about 7 times the hydrogen evolution performance of ZnCdS and 130 times that of NiAl LDH. This is primarily attributed to the close interface contact formed between rod-shaped ZnCdS and layered NiAl LDH, enhancing charge transfer for more efficient photocatalytic hydrogen evolution.

Summary: S-scheme In2S3/Zn3In2S6 microspheres were prepared to enhance photocatalytic H2 evolution and bisphenol A degradation. The microspheres consisted of embedded 2D In2S3 nanosheets in 2D-3D Zn3In2S6 hierarchical microspheres for improved light absorption and charge carrier separation. The photocatalytic H2 evolution rate of In2S3/Zn3In2S6 showed 15.7 and 7.9-fold enhancements compared to In2S3 and Zn3In2S6 separately, with bisphenol A degradation efficiency up to 95.8%. The S-scheme charge transfer mechanism maximized the redox capability of Zn3In2S6 for H2 evolution and In2S3 for bisphenol A degradation.

Summary: Researchers proposed a novel method to deposit sub-10 nm metallic Ni2P particles on the surface of graphitic carbon nitride (CN) for enhanced H-2 generation under visible light. The Ni2P-modified CN showed improved optical properties and electron shuttling capability, leading to a significantly increased H-2 production. However, the catalytic activity decreased after multiple reaction cycles due to the photo-corrosion of the Ni2P cocatalyst.
