Applications of Single-atom Catalysts in CO2 Conversion

Single-atom catalyst (SAC), emerging as a kind of promising catalyst materials with isolated active sites anchored on diverse matrixes, has shown excellent performances in thermocatalysis, photocatalysis and electrocatalysis due to their maximized efficiency of atoms and unique, adjustable electronic structure. Among all the reactions catalyzed by SAC, thermo/photo/electrocatalytic CO2 conversion reaction (CCR) converts CO2, the greenhouse gas, into fuels or value-added chemicals, which provides an effective strategy for solving the serious issues of global warming and energy shortage. In this perspective, based on the catalytic conversion of CO2 by SAC, the research progresses in the field of CO2 conversion reaction by SAC in recent years are summarized, the advantages and disadvantages of the synthetic methods, regulation and various CCRs are discussed,and the future development of SAC is prospected.
