Progress in the conversion of hydrogen peroxide and high-value-added chemicals by inorganic-organic heterojunction photocatalysts

Inorganic-organic hybrid materials have excellent optical absorption ability and high photocarrier separation efficiency, while retaining many advantages of inorganic and organic semiconductors, and have broad application prospects in the field of photocatalysis. Therefore, the synthesis methods, applications, and characterization methods of inorganic-organic hybrid materials are reviewed. Secondly, the applications of these photocatalysts in biomass catalytic conversion, CO2 conversion, H2 production, and hydrogen peroxide production are systematically analyzed. In addition, some advanced in-situ characterization methods and theoretical calculations are introduced to verify the catalytic mechanism of hybrid materials. Finally, the problems and challenges of inorganic-organic heterojunction photocatalysts are discussed, and suggestions for material design and improvement of photocatalytic performance are provided.
