Metal-organic frameworks (MOFs), composed of organic linkers and metal-containing nodes, are one of the most rapidly developing families of functional materials. The inherent features of MOFs, such as high specific surface area, porosity, structural diversity, and tunability, make them a versatile platform for a wide variety of interdisciplinary applications. Here, we review the recent advances in thermal energy storage by MOF-based composite phase change materials (PCMs), including pristine MOFs, MOF composites, and their derivatives. At the same time, this review offers in-depth insights into the correlations between MOF structure and thermal performance of composite PCMs. Finally, future opportunities and challenges associated with MOF-based composite PCMs are discussed.

由有机连接基和含金属的节点组成的金属有机框架（MOF）是功能材料发展最快的家族之一。MOF的固有功能，例如高比表面积，孔隙率，结构多样性和可调性，使其成为适用于多种跨学科应用的多功能平台。在这里，我们回顾了基于MOF的复合相变材料（PCM）在热能存储方面的最新进展，这些复合相变材料包括原始MOF，MOF复合材料及其衍生物。同时，本文对MOF结构与复合PCM的热性能之间的相关性提供了深入的见解。最后，讨论了与基于MOF的复合PCM相关的未来机遇和挑战。
