核壳结构将“客体”材料封装在保护壳内，整合了不同材料的优点，以增强复合材料的整体性能。共价有机骨架（COF）由于其固有的孔隙率、良好的活性、优异的稳定性等优点，是构成核壳结构的有利候选者。特别是，COF作为封装其他功能材料的外壳在环境修复和能源转换领域越来越受欢迎。然而，目前缺乏对基于COF的核壳材料的综述。在此背景下，本文系统总结了当前基于COF的核壳复合材料的研究。首先，对COF基核壳复合材料进行简单的分类。综述的第二部分描述了主要的合成方法。重点介绍了COF壳层和核壳结构对复合材料性能带来的变化及其在光催化、电催化、吸附、传感和超级电容器等方面的应用。最后，提出了复合材料未来发展和挑战的新观点。本研究的目的是为基于 COF 的核壳复合材料的设计和应用提供未来的见解。

Covalent–Organic Framework (COF)-Core–Shell Composites: Classification, Synthesis, Properties, and Applications

Core–shell structures, where the “guest” material is encapsulated within a protective shell, integrate the advantages of different materials to enhance the overall properties of the composite. Covalent–organic frameworks (COFs) are favorable candidates for composing core–shell structures due to their inherent porosity, good activity, excellent stability, and other advantages. In particular, COFs as shells to encapsulate other functional materials are becoming increasingly popular in the fields of environmental remediation and energy conversion. However, there is a lack of reviews on COF-based core–shell materials. In this context, this review provides a systematic summary of the current research on COF-based core–shell composites. First, a simple classification is made for COF-based core–shell composites. The second part of the review describes the main synthesis methods. The changes brought about by the COF shell and core–shell structures on the properties of the composites and their applications in photocatalysis, electrocatalysis, adsorption, sensing, and supercapacitors are then emphasized. Finally, new perspectives on the future development and challenges of composites are presented. The purpose of this study is to provide future insights into the design and application of COF-based core–shell composites.
