英文摘要The CO2 reduction reaction products of Co-based electrocatalysts are mainly CO and HCOOH, but there are few reports on hydrocarbons with the highest added value. Herein, a novel Co-based MOFs with V-type trinuclear cluster was constructed and exfoliated by ultrasound into ultrathin metal-organic nanosheets (similar to 3 nm) that retain the precursor structure. The Cobalt-based metal-organic nanosheets exhibits an excellent electrocatalytic reduction of CO2 performance with the relatively low overpotential of -0.4 V at the current density of 8.4 mA cm(-2) and the Faradaic efficiency of CH4 and C2H6 is 22.4 % and 11.6 %, respectively. The in-situ Raman spectroscopy and density functional theory calculations indicate that the catalytic sites of Co at both ends of the V-type cluster more easily convert *CO into intermediates of *COH therefore formation the removable *CH3, and they can be reduced to CH4 or coupled form C2H6 in the process of shedding and the environment of hydrogen evolution reaction.
