Recent progress of hydrogen-bonded organic framework-based photocatalysis

Abstract

Photocatalysis has emerged as a promising sustainable approach for solar-to-chemical energy conversion to deal with global energy and environmental issues. The newly developed hydrogen-bonded organic frameworks (HOFs) have attracted significant attention as novel photocatalysts owing to their low-energy synthesis, unique solution processability, as well as molecular-level designability and crystalline porous characteristics. So far, HOF-based photocatalysts have been applied in CO₂ reduction, water-splitting H₂ evolution, pollutant degradation, organic transformations, and so on. This review focuses on the fundamental understanding of HOF properties for photocatalysis and the recent achievements of HOF-based photocatalytic applications. Furthermore, perspectives on current challenges and future issues for HOF-based photocatalysts are proposed.
