Electrocatalytic reduction of oxygen (O 2 ) to produce hydrogen peroxide (H 2 O 2 ) frequently suffers from the low activity and poor selectivity of catalysts owing to the lack of systematic strategies. The resulting enhancement to enable the further design of a new bimetallic catalyst with the synergistic interplay, as exemplified by Cu-Pb catalyst for two-electron oxygen reduction reaction (2e - ORR), is reported here. Critically, in-depth evidence, including density functional theory (DFT) calculations, electrochemical signals, in-situ Raman, and H 2 O 2 -proof work, allude to a catalytic favor to the 2e - ORR of Cu-Pb.
