摘要
CO_(2)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 CO_(2)capture,separation,and conversion.Currently,Cu is a key metal in the catalytic CO_(2)reduction reaction(CO_(2)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 CO_(2)RR.Here,we mainly introduce the synthesis strategies,some important characterization information,and the applications of electrocatalytic and photocatalytic CO_(2)conversion using these previously reported Cu-based COFs.
CO_(2)还原技术能够推动碳的资源化利用,有助于缓解全球变暖及能源供应压力,是实现能量转换与利用的有效途径。共价有机框架(COFs)是由有机单体通过共价键连接形成的多孔晶体材料,具有功能多样、化学性质丰富等特点,其高孔隙率、宽可见光吸收范围和优异的电荷分离效率等优势,使其在CO_(2)的捕获、分离和转化方面表现出良好潜力。目前,Cu是催化CO_(2)还原反应中制备高附加值化学品的关键金属材料。利用COFs作为负载铜的理想牺牲模板,制备得到高稳定性和大孔结构的Cu基COFs,可以用于开发高性能电催化剂和光催化剂。在这篇综述中,我们讨论了该领域的最新研究进展,包括各种Cu基COFs的开发及其作为CO_(2)还原反应催化剂的应用。本文主要介绍了Cu基COFs的合成策略和一些重要的表征信息,以及其电催化和光催化CO_(2)转化的应用。
