Abstract:

The conversion of carbon dioxide into value-added carbon-containing chemicals or fuels through photo-catalytic technology is one of the sustainable ways to solve the energy crisis and greenhouse effect. However, it is a great challenge to pursue catalysts with high efficiency, low price, and high stability for improving the efficiency of photocatalytic reduction reaction of CO2(CO2RR). Single atom catalysts(SACs) have been widely studied in the field of catalysis because of their high atomic utilization and adjustable electronic environment. In photocatalysis of CO2RR, the addition of single metal atoms can not only adjust the energy band structure and the light adsorption ability of catalysts, but also effectively improve the efficiency of photogenerated charge transfer, and provide an ideal platform for the study of photocatalytic reaction mechanism. In recent years, the research of SACs in CO2RR has developed rapidly. In this paper, the progress of SACs of photocatalytic CO2RR is summarized, and the typical research results of SACs with different supports are introduced, and the future research trend is prospected.
