Covalent organic frameworks (COFs) are an emerging class of photoactive materials, solely composed of light elements. Their ordered structure, crystallinity, and high porosity led to enormous worldwide attention in many research fields. The extensive π-electron conjugation, light-harvesting and charge transport characteristics make them a fascinating polymer for photocatalytic systems. Versatile selection of building blocks and innumerable synthetic methodologies enable them to be a robust platform for solar energy production. In this mini-review, we summarized recent progress and challenges of the design, construction, and applications of COFs-based photocatalysts, and also presented some perspectives on challenges.
