Abstract

Anthropogenic CO2 emissions threaten the synergy between human society and the natural environment. To mitigate CO2 emissions, several CO2 utilization techniques have been proposed. Covalent organic frameworks (COFs), a promising class of porous crystalline materials, have been extensively explored for efficient CO2 utilization owing to their unique features. In particular, well-designed COFs with diverse active sites provide great opportunities to realize CO2 conversion. Herein, we review recent progresses in the design, synthesis, and catalytic mechanisms of COF-based functional materials for CO2 utilization reactions such as photo/electrocatalytic CO2 reduction, cycloaddition, carboxylation, and hydrogenation. We thoroughly evaluate and discuss photocatalytic CO2 reduction reactions using pristine and metalated COFs; CO2 electroreduction and carboxylation reactions using different metal-based COFs; and CO2 cycloaddition reactions using non-metalated, metalated, and ionic liquid-functionalized COFs. Finally, the challenges and prospects of CO2 utilization using COF-based catalysts are highlighted.
