ABSTRACT

In light of growing energy demand and pollution, it is important to develop a clean and renewable energy source. In recent years, photocatalysis, which harnesses solar energy to create fuels like hydrogen or to decompose pollutants, has shown a lot of promise in attaining this goal. Due to their high structural regularity, robust framework, intrinsic porosity, and high activity, covalent organic frameworks (COFs) are some of the most attractive photocatalysts. As a result, numerous investigations on the photocatalytic performance of COFs and COF-based photocatalysts have been conducted. The latest progress and advancements of COF photocatalysts are comprehensively covered in this critical evaluation. The morphologies of COFs, as well as numerous regularly employed photocatalytic techniques, are also reviewed. The applications of COF-based photocatalysts as hydrogen evolution are then discussed in detail. Furthermore, a conclusion and perspective on the possibilities and constraints of developing COF and COF-based photocatalysts are presented.
