摘要

Abstract

MOF-based materials have been widely explored in electrochemical CO

reduction reactions for the production of valuable chemicals. Understanding the reconstruction of those catalysts under working conditions is crucial for the identification of active sites and clarification of reaction mechanism. Herein

a series of six N coordinated Sn-based metal-organic frameworks (Sn-N6-MOFs) are newly developed for electrochemical CO

reduction (CO

RR). 2% Sn-N6-MOF achieves the optimal catalytic performance with a formate Faradaic efficiency of ~85% and a current density of 23 mA·cm
