An improved density functional theory-based H coverage-dependent electrochemical model with explicit solvent effect is proposed for Cu(111), which is used to identify potential-dependent initial competitive CO2 electroreduction pathways considering HER. We find that a chemisorbed CO2 molecule at the present electrode/aqueous interface can be spontaneously formed and the overpotentials can affect its coordination pattern. The Eley–Rideal mechanism may be more favorable during the initial CO2…
