Abstract Single-atom catalysts (SACs) have been a hot topic in the field of electrocatalysis because of their advantages of high selectivity, maximum metal utilization and unique electronic structure. However, the metal atoms are often agglomerated during SACs preparation due to their high surface free energy, resulting in a decrease in the number of catalytic active sites and the metal load, which seriously hinders the further development of SACs. In order to solve the problems of small number of single metal active sites and low metal loading capacity, the innovative development of dual-atom catalysts (DACs) as SACs has been studied in depth in recent years. Recently, dual-atom catalysts (DACs) have attracted considerable research interest since they exhibit higher metal atom loading and more flexible active sites compared to SACs. In this work, the application of homonuclear/heteronuclear DACs in electrocatalysis was summarized by introducing the preparation methods and characterization methods of homonuclear/heteronuclear DACs, and the challenges and future development directions in the field of electrocatalysis were briefly prospected.
