Covalent organic frameworks (COFs) are a class of materials that form two- or three-dimensional structures through reactions between organic precursors resulting in strong, covalent bonds to afford porous, stable, and crystalline materials. COFs emerged as a field from the overarching domain of organic materials as researchers optimized both synthetic control and precursor selection. These improvements to coordination chemistry enabled non-porous and amorphous … WebThis review focuses on the recent development of covalent organic frameworks (COFs)-based inorganic/organic composite materials for photocatalysis. The main synthesis strategies and the photocatalytic applications of the COFs-based inorganic/organic composite materials are reviewed to showcase the recent advances in the field and …
