摘要：

In this work, surface N-coordinated Cu (N-Cu) catalysts were developed by the direct calcination of a sole N-containing Cu-2(OH)(3)NO3 precursor followed by in situ electroreduction during CO2 electrolysis. The best N-Cu catalyst exhibits a CO2-to-ethylene (C2H4) faradaic efficiency (FE) of 73.2% with a partial current density of -700.8 mA cm(-2) at -1.09 V versus the reversible hydrogen electrode (RHE) in a flow cell, greatly outperforming surface N-free Cu catalysts.
