Photocatalysis has been widely studied because it can use inexhaustible solar energy as an energy source while solving the problems of fossil fuel depletion and environmental pollution facing the 21st century. Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), with many advantages such as high physical/chemical stability, tunable bandgap, structural diversity, large specific surface area, etc., are considered important propellants for building better photocatalytic platforms and achieving breakthroughs. This review outlines the applications of MOFs and COFs for photocatalysis in CO₂ reduction, H₂ generation, and environmental pollution treatment, and elucidates the relevant photocatalytic mechanisms. In particular, the methods and mechanisms for improving the photocatalytic performance of MOFs and COFs are summarized and discussed from the three aspects. Finally, the current limitations, challenges, perspectives and future development opportunities of COFs/MOFs and COF-/MOF-based photocatalysts are summarized and prospected.

光催化由于可以利用取之不尽的太阳能作为能源，同时解决了21世纪面临的化石燃料枯竭和环境污染问题，因此得到了广泛的研究。金属有机骨架（MOFs）和共价有机骨架（COFs）具有物理/化学稳定性高、带隙可调、结构多样性、比表面积大等优点，被认为是构建更好的光催化平台和提高光催化性能的重要推进剂。取得突破。本综述概述了 MOF和 COF 在光催化 CO ₂还原、H _{2中的应用}产生和环境污染处理，并阐明相关的光催化机制。特别从三个方面对提高MOFs和COFs光催化性能的方法和机理进行了总结和讨论。最后，总结和展望了COFs/MOFs和COF-/MOF基光催化剂目前的局限性、挑战、前景和未来发展机遇。
