Metal-Organic Frameworks (MOFs) and Their Derivatives for Electrocatalytic Carbon Dioxide (CO₂ ) Reduction to...

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.
