英文摘要Metal-organic frameworks (MOFs), combining the favorable characteristics of heterogeneous and homogeneous catalysts, have been explored as a novel class of model catalytic materials for understanding electrochemical CO2 reduction reaction (CO2RR). MOFs exhibit high Faradaic efficiency of CO2RR, but suffer from limited current density of CO2RR (typically lower than 3.4 mA cm(-2)). Herein, we investigate zeolitic imidazolate frameworks (ZIFs) including ZIF-8, ZIF-108, ZIF-7 and SIM-1 with the same SOD (sodalite) topology and different organic ligands for CO2RR in aqueous electrolyte. ZIF-8 shows the highest CO Faradaic efficiency of 81.0% at - 1.1 V (vs. reversible hydrogen electrode, RHE) among the four ZIF catalysts, and the highest CO current density can reach 12.8 mA cm(-2) at - 1.3 V (vs. RHE) over ZIF-108. In situ X-ray absorption spectroscopy measurements and density functional theory calculations indicate that the imidazolate ligands coordinated with the Zn(II) center in ZIFs are the active sites for CO2RR, determining the CO Faradaic efficiency and current density over ZIFs.
