The rise in global temperatures and environmental contamination resulting from traditional fossil fuel usage has prompted a search for alternative energy sources. Utilizing solar energy to drive the direct splitting of water for hydrogen production has emerged as a promising solution to these challenges. Covalent organic frameworks (COFs) are ordered, crystalline materials made up of organic molecules linked by covalent bonds, featuring permanent porosity and a wide range of structural topologies. COFs serve as suitable platforms for solar-driven water splitting to produce hydrogen, as their building blocks can be tailored to possess adjustable band gaps, charge separation capabilities, porosity, wettability, and chemical stability. Here, the impact of the interface in the context of the photocatalytic reaction is focused and propose strategies to enhance the hydrogen production performance of COFs photocatalysis. In particular, how hybrid photocatalytic interfaces affect photocatalytic performance is focused.
传统化石燃料的使用导致全球气温上升和环境污染，这促使人们寻找替代能源。利用太阳能驱动水的直接分解来制氢已成为应对这些挑战的一种有前景的解决方案。共价有机框架（COFs）是由通过共价键连接的有机分子组成的有序晶体材料，具有永久孔隙率和多种结构拓扑。COFs可作为太阳能驱动水分解制氢的合适平台，因为其构建单元可以进行定制，以具备可调节的带隙、电荷分离能力、孔隙率、润湿性和化学稳定性。在此，聚焦于光催化反应背景下界面的影响，并提出提高COFs光催化产氢性能的策略。特别关注混合光催化界面如何影响光催化性能。
