They are characterized by precise structure, unique electronic structure, and abundant active sites, which show potential applications in the field of catalysis. Among them, Ag-based nanoclusters have been applied in the field of electrocatalysis due to their good electrical conductivity, relatively low cost, and tunable structure. In this paper, we briefly introduce the recent research progress of Ag-based nanoclusters in electrocatalysis, including CO2 reduction, ammonia synthesis, oxygen reduction reaction, hydrogen precipitation reaction, and other reactions, summarize the factors affecting their catalytic performance (e.g., metal composition, type of ligand, etc.) and the corresponding catalytic mechanism, point out the challenges in the current research, and look forward to their future development direction.
