摘要

Electrocatalytic CO2 reduction reaction, namely CO2RR, provides a versatile way of storing energy in chemical bonds while simultaneously closing the anthropogenic carbon cycle.Producing valuable multicarbon products (C2+) from CO2RR is desirable yet challenging [1].It has been noted that oxide-/hydroxide-derived copper electrodes exhibit excellent selectivity toward C2+ products during CO2RR [2].However, the origin of such enhanced selectivity remains unclear, and the existence of Cu oxide species on electrode surface or subsurface at CO2RR conditions is still under debate [3].
