Enhanced Electrochemical O₂ -to-H₂ O₂ Synthesis Via Cu-Pb Synergistic Interplay

Electrocatalytic reduction of oxygen (O₂ ) to produce hydrogen peroxide (H₂ O₂ ) 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 H₂ O₂ -proof work, allude to a catalytic favor to the 2e^- ORR of Cu-Pb.
