Photocatalysis of Covalent Organic Frameworks

Abstract

The development of clean and sustainable energy is gaining attention in light of the current energy crisis and global warming. An ideal way to utilize renewable solar energy is to convert clean energy through photocatalysis. This includes splitting water, reducing CO2, regenerating coenzymes, etc. Photocatalysis relies heavily on photocatalysts. It has recently become popular to use organic porous polymers in this process. Covalent organic frameworks (COFs), as one of the organic porous polymers, have the characteristics of high crystallinity, porosity, and structural designability that make them perfect platforms for photocatalysis. An overview of recent advances in COF photocatalysts is presented in this chapter. The photocatalytic applications of COFs with different ligation and different structures were first discussed, including photocatalytic hydrogen evolution, CO2 conversion, coenzyme regeneration, and conventional organic reactions. Finally, conclusions and prospects were provided in the last section.
