Metal-organic frameworks (MOFs) with orderly porous structure, large surface area, high electrochemical response and chemical tunability have been widely studied for energy conversion and storage. However, most reported MOFs still suffer from poor stability, insufficient conductivity, and low utilization of active sites. One strategy to circumvent these issues is to optimize MOFs via designing composites. Here, the design principle from the viewpoint of the intrinsic relationships among various components will be illuminated to acquire the synergistic effects, including two working modes: (1) MOFs with assistant components, (2) MOFs with other function components. This review introduces recent research progress of MOF-based composites with their typical applications in energy conversion (catalysis) and storage (supercapacitor and ion battery). Finally, the challenges and future prospects of MOF-based composites will be discussed in terms of maximizing composite properties.

用于能量转换和存储的金属有机骨架复合材料

具有有序多孔结构、大表面积、高电化学响应和化学可调性的金属有机骨架 (MOF) 已被广泛研究用于能量转换和存储。然而，大多数报道的 MOF 仍然存在稳定性差、导电性不足和活性位点利用率低的问题。规避这些问题的一种策略是通过设计复合材料来优化 MOF。在这里，将从各个组件之间的内在关系的角度阐明设计原理以获得协同效应，包括两种工作模式：（1）具有辅助组件的MOF，（2）具有其他功能组件的MOF。本综述介绍了基于 MOF 的复合材料的最新研究进展及其在能量转换（催化）和存储（超级电容器和离子电池）方面的典型应用。
