Covalent Organic Framework Based Functional Materials: Important Catalysts for Efficient CO2Utilization

Abstract As hot topics in the chemical conversion of CO 2 , the photo‐/electrocatalytic reduction of CO 2 and use of CO 2 as a supporter for energy storage have shown great potential for the utilization of CO 2 . However, many obstacles still exist on the road to realizing highly efficient chemical CO 2 conversion, such as inefficient uptake/activation of CO 2 and mass transport in catalysts. Covalent organic frameworks (COFs), as a kind of porous material, have been widely explored as catalysts for the chemical conversion of CO 2 owing to their unique features. In particular, COF‐based functional materials containing diverse active sites (such as single metal sites, metal nanoparticles, and metal oxides) offer great potential for realizing CO 2 conversion and energy storage. This Minireview discusses recent breakthroughs in the basic knowledge, mechanisms, and pathways of chemical CO 2 conversion strategies that use COF‐based functional catalysts. In addition, the challenges and prospects of COF‐based functional catalysts for the efficient utilization of CO 2 are also introduced.
