a Methane FEs on 7% Au–Cu at various CO2 concentrations. b Ethylene FEs on 7% Au–Cu at various CO2 concentrations. c CH4 cathodic EEs at different current densities under different CO2 concentrations. d Comparison of \({\rm{FE}}_{{\rm{CH}}_{4}}/{\rm{FE}}_{{\rm{C}}_{2+}}\) ratios on 7% Au–Cu catalysts at various CO2 concentrations. Error bars represent the standard deviation based on three separate measurements.
