Porous Materials for CO 2 RR

Electrocatalytic carbon dioxide reduction reaction (CO 2 RR) can effectively activate inert carbon dioxide molecules into more helpful fuels and chemicals for human life, which is considered to be one of the most potential ways to achieve the goal of carbon neutralization in the future. So far, using electrocatalytic technology to reduce CO 2 molecules into single-carbon products is very mature, but it is still a great challenge to obtain multicarbon products with more practical values. For this reason, it is urgent to design and synthesize electrocatalysts with ultrahigh selectivity, stability, and excellent activity. Crystalline porous materials (such as metal–organic framework (MOF), covalent organic framework (COF), and their corresponding derived porous materials) provide great opportunities for the activation and transformation of CO 2 because of their large specific surface area, high porosity, controllable structure and morphology, and modified framework, making them a promising candidate material for CO 2 RR. This chapter summarizes in detail the latest research progress on porous materials as typical functional porous framework catalysts in the field of CO 2 RR, providing new horizons and ideas for future exploration in this important field.
