摘要：

Solar-driven conversion of CO2 and CH4 to syngas is a very promising technology for producing renewable fuels. However, solar-driven CH4 reforming catalysts suffer from low conversion efficiency, fast photogenerated electron-hole complexation rate and poor catalyst stability. This paper briefly describes the possible mechanisms of photocatalytic CO2 and CH4 reforming, including the adsorption of CO2 and CH4, the migration of photogenerated electrons and holes and the desorption of products. The research progress of precious metal catalysts, non-precious metal catalysts and carbon-nitrogen compounds for the photocatalytic CO2 and CH4reforming is highlighted, and the advantages and shortcomings of these catalysts are also summarized. Finally, this paper discusses the possible development directions in the field of photocatalytic conversion of CO2 and CH4 to syngas, i.e. the development and design of efficient photocatalysts to improve the reaction efficiency, catalytic mechanism investigation by density functional theory (DFT) and advanced characterization techniques. © 2023 Chemical Industry Press.
