Carbon dioxide electrolysis on the silver–copper and bare silver surfaces. Faradaic efficiencies (a) and partial current densities (b) of CO2 electrolysis products on the Ag-Cu surface achieved at a Cu2+ concentration of 1.5 ppm. Faradaic efficiencies (c) and partial current densities (d) of CO2 electrolysis products on a bare polycrystalline Ag surface. The error bars represent the standard deviation from at least three independent measurements
