Abstract Silver–copper (Ag–Cu) bimetallic nanoalloys were prepared by electrodeposition methods and their microstructure, morphology and electrocatalytic properties were characterized by XRD, HRTEM, SEM and electrochemical workstation. The results show that the silver–copper bimetallic nanoalloy electrodes exhibit a large reduction current peak in H2O2 solutions, indicating that silver-copper bimetallic nanoalloy can be used as a cathode catalytic. The morphology of silver-copper bimetallic nanoalloys changes from spiciform crystal to dendritic crystal and the cathode catalytic performance decreases with increasing deposition potential; The morphology of the nanoalloys changes from dendritic crystal to rod-shaped crystal and the cathode catalytic performance increases with the increasing of Cu2+ concentrations. It can be concluded that the synergistic effects are observed in the electrocatalytic performance for silver-copper bimetallic nanoalloys.
