Summary: The development of high-activity photocatalysts for the large-scale industrial application of photocatalytic selective conversion of biomass alcohols into value-added chemicals and H2 evolution in aqueous solution is still a challenge. In this study, ReS2 was used as a high-efficiency co-catalyst to modify flower-like ZnIn2S4 microspheres, resulting in significant enhancements in the photocatalytic oxidation of furfural alcohols combined with H2 evolution. The optimal catalyst, RZIS-3, containing 4.08 wt% ReS2, achieved remarkably high generation rates of H2 and furfural at 3092.9 and 2981.1 mmol g-1 h-1, respectively, nearly 12 times faster than blank ZnIn2S4. Mechanism studies confirmed that the migration of photogenerated carriers from ZnIn2S4 to ReS2 was responsible for the enhanced photoactivity of the composite. Furthermore, the composite showed high performance in the oxidation of other alcohol biomass intermediates, providing valuable insights for the design and fabrication of novel photocatalytic hydrogen evolution systems.

Summary: Simultaneously utilizing photogenerated electrons and holes to convert renewable biomass and its derivatives into value-added products and hydrogen (H-2) is a promising strategy. In this study, a facile hydrothermal method is used to construct a direct Z-scheme CdS/WO3 binary composite for photocatalytic coupled redox reaction, producing H-2 and selectively converting aromatic alcohols into aromatic aldehydes in one pot. The CdS/WO3 binary composite exhibits significantly enhanced performance compared to bare CdS and WO3, attributed to its extended light harvesting range, efficient charge carrier separation rate, and optimized redox capability. The feasibility of converting various aromatic alcohols to aldehydes coupled with H-2 evolution on the CdS/WO3 photocatalyst is demonstrated, along with a proposed reaction mechanism.

Summary: Introducing oxygen vacancies (Vo) into TiO2 photocatalyst along with N doping is proposed as an alternative strategy for achieving efficient co-catalyst-free solar photocatalytic activity under less extreme conditions. The synthesized material exhibits good co-catalyst-free solar photocatalytic activity for hydrogen evolution via water splitting under irradiation with simulated solar light, showing higher efficiency compared to typical co-catalyst-free defective TiO2 materials. The introduced Vo is believed to play a role in facilitating charge separation and improving photocatalytic efficiency.

Summary: The study introduces an effective electrochemical lithiation method for the synthesis of lithium-intercalated TiO2 nanoparticles, improving their photocatalytic hydrogen production performance. The electrochemical lithiation of TiO2 leads to a partial reduction of Ti ions in the crystal lattices, introducing additional energy states and enhancing the optical properties. As a result, Li-intercalated TiO2 NPs exhibit significantly higher hydrogen generation activity under both UV and visible light exposure compared to commercial TiO2 NPs (P25).

Summary: Decorating single atoms of transition metals on MXenes enhances the electrocatalytic properties of the resulting composites. In this study, cobalt single atoms were anchored onto several commonly used MXene substrates, and the electrocatalytic behavior and mechanisms were systematically studied. The Co@V2CTx composite showed lower overpotentials for oxygen and hydrogen evolution reactions compared to other composites, making it comparable to commercial noble metal electrocatalysts. The enhanced catalytic performance of Co@V2CTx was attributed to optimized electronic structure and accelerated catalytic kinetics. This study sheds light on the origins and guidelines for designing efficient MXene-based electrocatalysts.
