共价有机框架材料在光催化领域中的应用

Covalent organic frameworks(COFs) are crystalline porous organic materials, which are built from organic building blocks through covalent bonds. COFs have the characteristics of well-defined pore structure and high specific surface area. COFs have been widely used in gas storage and separation, catalysis, sensing, energy storage, photoelectric conversion and many other fields. Introducing organic building blocks with adjustable light absorption into COFs provide COF with a great potential in photocatalysis. In recent years, COFs have developed rapidly in the field of photocatalysis. This paper summarizes the recent progress of COFs in the fields of photocatalytic hydrogen production, photocatalytic carbon dioxide reduction, photocatalytic organic reactions, and photocatalytic degradation of pollutants, and looks forward to its further prospects in the field of photocatalysis.
