Abstract Two-dimensional covalent organic frameworks (COFs) are an emerging class of semiconducting materials for photocatalysis solar fuel production. They uniquely feature compositional and structural diversities (as opposed to inorganic semiconductors) as well as high crystallinity (as opposed to other organic semiconductors), and thereby hold great potential that is just beginning to be unveiled. Here, we provide an up-to-date account of the latest advances on the design and engineering of COF-based materials for photocatalytic H2 production or CO2 reduction. The review begins with an introduction of the background and fundamentals about COF-based photocatalysis. It is then followed by discussion about recent progress on their preparation, understanding of charge dynamics and strategies for improving photocatalytic performances. A short perspective on the opportunities and further directions is presented at the end.

用于光催化太阳能燃料生产的二维半导体共价有机框架

摘要 二维共价有机骨架（COFs）是一类新兴的用于光催化太阳能燃料生产的半导体材料。它们具有独特的成分和结构多样性（与无机半导体相反）以及高结晶度（与其他有机半导体相反），因此具有刚刚开始显现的巨大潜力。在这里，我们提供了用于光催化 H2 生产或 CO2 还原的基于 COF 的材料的设计和工程的最新进展的最新说明。综述首先介绍了基于 COF 的光催化的背景和基本原理。随后讨论了其制备的最新进展、对电荷动力学的理解以及提高光催化性能的策略。
