Abstract

Abstract: Atomically dispersed metal catalysts with well‐defined structures have been the research hotspot in heterogeneous catalysis because of their high atomic utilization efficiency, outstanding activity, and selectivity. Dual‐atomic‐site catalysts (DASCs), as an extension of single‐atom catalysts (SACs), have recently drawn surging attention. The DASCs possess higher metal loading, more sophisticated and flexible active sites, offering more chance for achieving better catalytic performance, compared with SACs. In this review, recent advances on how to design new DASCs for enhancing energy catalysis will be highlighted. It will start with the classification of marriage of two kinds of single‐atom active sites, homonuclear DASCs and heteronuclear DASCs according to the configuration of active sites. Then, the state‐of‐the‐art characterization techniques for DASCs will be discussed. Different synthetic methods and catalytic applications of the DASCs in various reactions, including oxygen reduction reaction, carbon dioxide reduction reaction, carbon monoxide oxidation reaction, and others will be followed. Finally, the major challenges and perspectives of DASCs will be provided. Abstract : As an extension of single‐atom catalysts, dual‐atomic‐site catalysts (DASCs) with high metal loading, sophisticated and flexible active sites have aroused great interest. The recent development of DASCs in characterization, synthetic methods, and catalytic applications are reviewed.
