Structural Engineering of Metal‐Organic Frameworks for Efficient CO2 Reduction Reaction

Abstract Metal‐organic framework (MOF) materials have attracted much attention due to their diverse topological structures, excellent adsorption capacity, and unique physicochemical properties, which hold great promise in catalytic CO 2 reduction reaction (CO 2 RR). However, the original MOFs materials have disadvantages such as poor electrical conductivity, high diffusion barrier and limited accessible catalytic sites, which seriously limit their application in CO 2 RR. Therefore, many structural engineering strategies have been used to improve the CO 2 RR performance of the MOFs materials. In this review, we mainly review the four main structure engineering strategies, i. e. crystal engineering, 2D engineering, heterostructure engineering and MOF derivatives engineering, in enhancing the catalytic CO 2 RR performance of the MOFs. We hope that this review will not only provide insights for the rational design of efficient MOFs materials for the CO 2 RR, but also stimulate more research work in this field.
