摘要：

Two typical Cu-based complex catalysts with piperazine (PR) and p-phenylenediamine (pPDA) ligands were designed to elucidate whether the ligands can tailor the reduction behavior of the Cu species and thus modulate their electrochemical CO2 reduction reaction (eCO(2)RR) activity. Specifically, Cu-PR underwent a significant in situ transformation into Cu nanoparticles enriched with a Cu delta+/Cu-0 interface for high eCO(2)RR activity, compared to Cu-pPDA. This finding reveals the importance of ligand engineering in modulating the eCO(2)RR performance of Cu-based complexes.
