a The C2H4 partial current density near the onset potentials. b Tafel plots for C2H4. In situ Raman peaks for CO adsorption on c Cu0.9Zn0.1 and d Cu at various potentials during CO2R. e In situ Raman peaks at 250–470, 1750–2300 cm−1 and 2700–3200 cm−1. f C2+/C1 FEs. Error bars represent the standard deviation based on three independent measurements. All potentials are with respect to the reversible hydrogen electrodes (RHE).
