Hetero-Interfaces on Cu Electrode for Enhanced Electrochemical Conversion of CO₂ to Multi-Carbon Products.

ABSTRACT: 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 ZrO_x nanoparticles (a-ZrO_x), constructing a-ZrO_x/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
