Abstract

Copper phthalocyanine on carbon (CuPc/C) after pyrolysis exhibits a C₂H₄ Faradaic efficiency (FE_C₂H₄) of 42.6 ± 0.5% at an extremely low potential of −0.4 V vs. RHE toward the electrochemical CO₂ reduction reaction (CO₂RR), significantly boosted by the in situ oxygen reduction reaction (ORR).
