摘要
金属有机骨架(MOFs)和共价有机骨架(COFs)是一系列结晶多孔材料。由于其高度有序的结构、高的表面积、可调的孔径和拓扑结构、富含氧化还原活性位点的连续骨架,MOFs和COFs及其衍生物在储能领域引起了广泛关注。为了制造高性能超级电容器电极,MOFs和COFs及其衍生物具有结构稳定性好、氧化还原活性位点丰富和电子导电性高等特征。本文回顾了近年来MOFs和COFs材料、MOFs和COFs与导电材料(导电聚合物、石墨烯、碳纳米管)的复合材料、MOFs和COFs衍生炭材料的设计策略,以及所得材料的物化特性、电容性能的研究进展,并介绍了结构和性能之间的关系。最后,提出了基于MOFs和COFs电极材料的挑战和前景。
Metal-organic frameworks(MOFs) and covalent organic frameworks(COFs) are both a series of crystalline porous materials. MOFs, COFs and their derivatives have attracted much attention in energy storage devices due to their highly ordered structures, large surface areas, tunable pore sizes and topologies, and well-defined redox-active porous skeletons. They must also have structural stability, an abundance of redox-active sites and high electronic conductivity for use in high-performance supercapacitor electrodes. We review the recent research progress on the design of MOFs and COFs, and their hybrids with conductive materials(e.g. conductive polymer, graphene and carbon nanotubes), and MOF-and COF-derived carbon materials. Their chemical and physical properties, capacitive performance and structure-property relationships are discussed. Finally, the challenges and prospects of MOF-and COF-based electrode materials are presented.
