Abstract

We present a Cu/PTFE electrode for the CO₂ reduction reaction with a high coverage of *OH which facilitates both the activation of CO₂ and the C–C coupling, leading to a faradaic efficiency for ethylene exceeding 50% at an exceptionally low potential of −246 mV vs. RHE, with the maximum FE_C₂H₄ reaching 60.3%.
