Abstract

To understand a high selectivity for HCOOH on the Pb electrode during the CO₂ reduction reaction, we suggest a proton-assisted-electron-transfer mechanism, and validate the new mechanism by experimentally measuring onset potentials for CO₂ reduction vs. H₂ production. We find that the origin of this high selectivity lies in the strong O-affinitive and weak C-, H-affinitive characteristics of Pb.
