Recent progress on covalent organic frameworks for photocatalytic hydrogen generation via water splitting

Abstract

Currently, the excessive consumption of conventional fossil fuels has caused the energy crisis and environmental pollution. Efficient solar-driven photocatalysts for the hydrogen evolution reaction (HER) are essential to facilitate future hydrogen-powered technologies. Covalent organic frameworks (COFs) with permanent porosity, long-range order and rigid backbones offer a promising material platform to address the global energy need. In this review, we focus on different strategies to improve the performance of COF-based photocatalysts and the factors involved in photocatalytic water splitting for hydrogen production. Finally, an overview on the prospects and challenges in the rational design of COF-based photocatalysts in the field of photocatalysis is outlined.
