Abstract

A novel type of electron donor-acceptor system was built from a nitrogen-rich covalent organic framework (PC) and a polyoxometalate (BW₁₂), fabricating a composite material (BW₁₂@PC-250), which shows significantly improved photocatalytic H₂O₂ yield (56.4 μM h^-1) under full spectrum illumination in pure water, being about 30 times higher than that of PC. This is due to the opening of the electron and proton transport pathway between PC and BW₁₂, which paves a new way for POMs to modulate the photocatalytic reactions of COFs.
