a The Schematic of the membrane electrode assembly equipped with a TPE. b Comparison of CO2 SPC of pentyl-CuCP and Cu2O. c C2+ product partial current density obtained using pentyl-CuCP and Cu2O. d The FE of C2H4 using pentyl-CuCP in 7-h electrolysis at 180 mA cm−2. e FEC2H4 and full-cell voltage in CO2RR coupled with HzOR. The Cu content in the Cu2O control group was consistent with that in the pentyl-CuCP. The error bars in (b), (c), and (d) correspond to the standard deviations of three independent measurements.
