Metal‐Organic Frameworks (MOFs) and Their Derivatives for Electrocatalytic Carbon Dioxide (CO2) Reduction to Value‐added Chemicals: Recent Advances and New Challenges

Excess CO2 can be effectively converted into valuable fuels and chemicals by electrochemical CO2 reduction, which can help establish a low-carbon emission economy and solve the current energy crisis. In recent years, metal-organic frameworks (MOFs), as an emerging multifunctional material with porous structure, high chemical tunability and large specific surface area, has received increasing attention in the field of electrochemical CO2 RR. In this paper, we present a comprehensive overview of various MOFs and their derivatives as CO2 RR electrocatalysts and analyze their roles in the catalytic process from physical and chemical aspects. In addition, combining experiments and theory, this article also offers a personal view on the electronic structure modulation strategies to improve electrocatalytic performance. The article concludes with an analysis of the challenges in realizing MOFs and their derivatives for electrocatalytic CO2 RR applications.
