A photo-active hollow covalent organic frameworks microcapsule imparts highly efficient photoredox catalysis of gaseous volatile organic compounds

Covalent organic frameworks (COFs) with controlled porosity, high crystallinity, diverse designability and excellent stability are very attractive in metal-free heterogeneous photocatalysis of volatile organic compounds (VOCs) degradation. In order to construct the high optimal performance COFs under feasible and universal conditions, herein, the visible light-driven hollow COF
