摘　　要：由于COFs具有半导体性质、可调的结构以及丰富的金属配位位点,在光催化CO_(2)还原领域引起了许多关注.本文从功能结构与活性位点等方面综述了基于COFs的光催化系统在CO_(2)还原方面的研究进展.首先讨论了无金属本征COFs的优缺点,由于无金属COFs缺少活性位点,通常情况下活性较低.在COFs中引入金属活性位点或构建异质结是提升光催化性能的良好策略.介绍了单金属COFs与多金属COFs材料,讨论了在COFs中引入金属活性位点的利弊.介绍了三种常见的异质结,讨论了构建异质结对COFs光催化剂性能提升起到的作用,以及目前尚且存在的弊端.最后,从COFs的合成、结构设计、机理研究以及环境与经济因素等方面概述了用于光催化还原CO_(2)的COFs的挑战和发展.COFs are attracting more and more interest in photocatalytic CO_(2)reduction because of their semiconductor properties,tunable structure,and abundant metal coordination sites.In this review,the progress of COF-based photocatalytic systems for CO_(2)reduction is summarized from the aspects of functional structures and active sites.First,we introduce metal-free intrinsic COFs,which show relatively low activity due to the lack of active sites.Introducing metal active sites or constructing heterojunctions in COFs is an effective strategy to improve photocatalytic efficiency.We discuss single metal COFs and multi-metal COFs materials from the advantages and disadvantages of the construction of metal active sites in COFs.Meanwhile,three type of commonly used heterojunctions are clarified.The importance of the construction of heterojunctions in improving the performance of COFs photocatalysts and the existing problems are described.Finally,we summarize the challenges and opportunities of COFs for photocatalytic CO_(2)reduction from synthesis,structural design,mechanism,and environmental and economic benefits.
