Hetero-Interfaces on Cu Electrode for Enhanced Electrochemical Conversion of CO2 to Multi-Carbon Products
文献摘要：
Electrochemical CO2 reduction reaction(CO2RR)to multi-carbon products would simultaneously reduce CO2 emission and produce high-value chemicals.Herein,we report Cu electrodes modified by metal-organic framework(MOF)exhibiting enhanced electrocatalytic performance to convert CO2 into ethylene and ethanol.The Zr-based MOF,UiO-66 would in situ transform into amorphous ZrOx nanoparticles(a-ZrOx),constructing a-ZrOx/Cu hetero-interface as a dual-site catalyst.The Faradaic efficiency of multi-carbon(C2+)products for optimal UiO-66-coated Cu(0.5-UiO/Cu)electrode reaches a high value of 74％at-1.05 V versus RHE.The intrinsic activity for C2+products on 0.5-UiO/Cu electrode is about two times higher than that of Cu foil.In situ surface-enhanced Raman spectra demonstrate that UiO-66-derived a-ZrOx coating can promote the stabilization of atop-bound CO* intermediates on Cu surface during CO2 electrolysis,leading to increased CO* coverage and facilitating the C-C coupling process.The present study gives new insights into tailoring the adsorption configurations of CO2RR intermediate by designing dual-site electrocatalysts with hetero-interfaces.
