摘要:

通過模仿自然界光合作用利用光催化材料實現太陽能到化學能的轉換，是解決地球能源問題和環境危機的有效途徑之一。二維共價有機框架材料具備結構可設計性強、結晶性高以及表面活性位點豐富等優勢，已經被廣泛用于光催化分解水制氫、二氧化碳還原以及制備過氧化氫等領域，近年來成為了太陽能光化學轉換研究領域的新興材料。綜述了近年來二維共價有機框架材料在光催化能量轉換領域的最新研究進展，重點探討了二維共價有機框架材料的材料設計與合成策略及其在光催化領域的典型應用，并展望此類材料在未來太陽能光化學轉換應用領域的機遇和挑戰。

Abstract:

Converting solar energy into chemical energy through artificial photosynthesis represents one of the most promising approaches to address the global energy crisis and environmental issues. Recently, two-dimensional covalent organic frameworks (COFs) have emerged as a promising class of photocatalysts for water splitting, CO2 reduction and hydrogen peroxide production as they generally possess versatile chemical structures, high crystallinity, and rich surface active sites. In this report, we highlight recent progress in developing two-dimensional COFs for solar-to-chemical energy conversion with emphasis on the design and synthetic strategies and corresponding applications in photocatalytic reactions. Furthermore, future opportunities and challenges in the field of solar-to-energy conversion are also briefly discussed.
