A LSV curves acquired in flow cell using 1 M KOH as electrolyte, where the curves were calibrated by iR compensation with a resistance value of 2.65 ± 0.3 Ω. B, C Faradic efficiencies of products at various jtotal using CuP/Cu2O (B) and CuL/Cu2O (C) catalysts. D C2+ and C2+ alcohols partial current density of CuP/Cu2O and CuL/Cu2O catalysts. E, F Energy efficiencies (E) and production rate (F) of C2+ alcohols on CuP/Cu2O and CuL/Cu2O catalysts. G Electrochemical stability test at the jtotal of 200 mA cm−2 using the CuL/Cu2O catalysts. Error bars show the standard deviations calculated from three independent experiments.
