Electrochemical CO reduction reaction (CO RR) is an attractive pathway to convert CO into value-added chemicals and fuels. Copper (Cu) is the most effective monometallic catalyst for converting CO into multi-carbon products, but suffers from high overpotentials and poor selectivity. Therefore, it is essential to design efficient Cu-based catalyst to improve the selectivity of specific products. Due to the combination of advantages of organic and inorganic composite materials, organic-inorganic composites exhibit high catalytic performance towards CO RR, and have been extensively studied. In this review, the research advances of various Cu-based organic-inorganic composite materials in CO RR, i. e., organic molecular modified-metal Cu composites, Cu-based molecular catalyst/carbon carrier composites, Cu-based metal organic framework (MOF) composites, and Cu-based covalent organic framework (COF) composites are systematically summarized. Particularly, the synthesis strategies of Cu-based composites, structure-performance relationship, and catalytic mechanisms are discussed. Finally, the opportunities and challenges of Cu-based organic-inorganic composite materials in CO RR are proposed.
电化学一氧化碳还原反应（CO RR）是将CO转化为高附加值化学品和燃料的一条具有吸引力的途径。铜（Cu）是将CO转化为多碳产物最有效的单金属催化剂，但存在高过电位和选择性差的问题。因此，设计高效的铜基催化剂以提高特定产物的选择性至关重要。由于有机和无机复合材料的优势相结合，有机-无机复合材料对CO RR表现出高催化性能，并已得到广泛研究。在本综述中，系统总结了各种铜基有机-无机复合材料在CO RR中的研究进展，即有机分子修饰的金属铜复合材料、铜基分子催化剂/碳载体复合材料、铜基金属有机框架（MOF）复合材料和铜基共价有机框架（COF）复合材料。特别讨论了铜基复合材料的合成策略、结构-性能关系和催化机理。最后，提出了铜基有机-无机复合材料在CO RR中的机遇和挑战。
