摘 要：Single atom catalysts(SACs)are constituted by isolated active metal centers,which are heterogenized on inert supports such as graphene,porous carbon,and amorphous *** thermal stability,electronic properties,and catalytic activities of the metal center can be controlled via manipulating the neighboring heteroatoms such as nitrogen,oxygen,and *** to the atomical dispersion of the active catalytic centers,the amount of metal required for catalysis can be ***,new possibilities are offered to easily control the selectivity of a given transformation process as well as to improve turnover frequencies and turnover numbers of target *** them,Fe–N–C single atom catalysts own special electronic structure,and have been widely used in many fields of *** review aims to summarize the synthesis of Fe–N–C based on anchoring individual iron atoms on carbon/*** spin-related properties of Fe–N–C catalysts are described,including the relation between spin and electron structure of Fe–N x as well as the coupling between electronic structure of Fe–N x and electronic(orbit)of CO_(2),N_(2)and O_(2).Next,mechanistic investigations conducted to un-derstand the specific behavior of Fe–N–C catalysts are highlighted,including C,N,O ***,some issues related to the future developments of Fe–N–C are put forward and corresponding feasible solutions are offered.
