【Abstract】 CO₂ reduction technology can promote the resource utilization of carbon and help alleviate global warming and energy supply pressure. It is an effective way to achieve energy conversion and utilization. Covalent organic frameworks（COFs） are porous crystalline materials formed by connecting organic monomers through covalent bonds. They have the characteristics of functional diversity and rich chemical properties. Their advantages, such as high porosity, a wide range of visible light absorption, and excellent charge separation efficiency, give them good potential in CO₂ capture, separation, and conversion. Currently, Cu is a key metal in the catalytic CO₂ reduction reaction（CO₂ RR） for the preparation of high-value-added chemicals. The preparation of highly stable and large-pore Cu-based COFs using COFs as an ideal sacrificial template for loading Cu can be used to develop high-performance electrocatalysts and photocatalysts. In this review, we discuss the latest advancements in this field, including the development of various Cu-based COFs and their applications as catalysts for CO₂ RR. Here, we mainly introduce the synthesis strategies, some important characterization information, and the applications of electrocatalytic and photocatalytic CO₂ conversion using these previously reported Cu-based COFs.更多还原
