Stabilizing oxidation state of Cu (Cuδ+, δ > 0) sites is the key-enabling issue for electrocatalytic carbon dioxide (CO2) reduction reaction (eCO2RR) to multicarbon (C2+) products. The present study addresses this challenge by introducing cerium (Ce) doping into La2CuO4. Ce facilitates f-d orbital coupling between 4f and 3d orbitals, suppressing electron enrichment around atoms transferring electrons from orbitals via a Cu-O-Ce chain. These changes modulate electronic structure Cu, reduce distance neighboring atoms, optimize binding energy surface-adsorbed CO (*CO), lower barrier *CO dimerization. As result, La1.95Ce0.05CuO4 catalyst achieves Faradaic efficiency up 81% C2+ products maintains high stability over 50 h operation. This work highlights unique role in stabilizing Cuδ+ hence enhancing C-C coupling, providing pathway designing efficient catalysts eCO2RR.
