摘　　要：单原子催化剂(SAC)是由互相隔离分散的原子级活性位点锚定在基底上而形成的一类新兴催化剂材料,其具有最大化的原子利用率、可调控的独特电子结构,因而在热催化、光催化及电催化等方面展现出良好的应用前景.通过SAC的热/光/电催化CO_(2)转化反应(CCR)能将温室气体CO_(2)转化为燃料或具有附加值的化学品,为解决严重的全球变暖和能源短缺问题提供了一种有效策略.本文总结了近年来SAC在CO_(2)转化领域的研究进展,讨论了其合成、调控及催化各类CO_(2)转化反应的优缺点,并对其未来的发展进行了展望.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 electrocataly⁃sis due to their maximized efficiency of atoms and unique,adjustable electronic structure.Among all the reactions catalyzed by SAC,thermo/photo/electrocatalytic CO_(2) conversion reaction(CCR)converts CO_(2),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 CO_(2) by SAC,the research progresses in the field of CO_(2) 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.
