Enhanced Electrochemical O₂‐to‐H₂O₂ Synthesis Via Cu‐Pb Synergistic Interplay

Abstract Electrocatalytic reduction of oxygen (O₂) to produce hydrogen peroxide (H₂O₂) 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 H₂O₂‐proof work, allude to a catalytic favor to the 2e⁻ ORR of Cu‐Pb.
