Conductive Metal/Covalent Organic Frameworks for CO_(2) Electroreduction

Porous crystalline metal-organic frameworks(MOFs)and covalent organic frameworks(COFs)are promising platforms for electrocatalytic reduction of CO_(2)(CO_(2)RR)due to their large CO_(2)adsorption uptakes and periodically arranged single active sites.However,the applications in CO_(2)RR of the traditional MOFs and COFs are greatly limited by their low electron conductivity.In recent years,numerous types of MOFs and COFs with high intrinsic conductivity have been rationally designed and successfully constructed,and some of them have been applied in CO_(2)RR.In this review,the applications of conductive MOFs and COFs in CO_(2)RR have been summarized.The conductive MOFs and COFs can be categorized according to the methods,in which the conductivity is enhanced,such as constructing fullyπ-conjugated backbones,donor-acceptor heterojunction,enhancing theπ-πstacking interactions between organic moieties and/or the introduction of guest molecules.
