外文摘要：To improve the electrocatalytic transformation of carbon dioxide(CO2)to multi-carbon(C2+)products is of great importance.Here we developed a nitrogen-doped Cu catalyst,by which the maximum C2+Faradaic efficiency can reach 72.7％in flow-cell system,with the partial current density reaching 0.62 A cm-2.The in situ Raman spectra demonstrate that the*CO adsorption can be strengthened on such a N-doped Cu catalyst,thus promoting the*CO utilization in the subsequent C-C coupling step.Simultaneously,the water activation can be well enhanced by N doping on Cu catalyst.Owing to the synergistic effects,the selectivity and activity for C2+products over the N-deoped Cu catalyst are much improved.
