Abstract
AbstractThree pyrene‐4,5,9,10‐tetraone‐based porous aromatic frameworks (PT‐PAFs) are synthesized and their photocatalytic properties for H2O2 production are studied. It is found that the combination of pyrene‐4,5,9,10‐tetraone with anthraquinone affords an efficient PT‐PAF photocatalyst (PAF‐371) for H2O2 production, which achieves production rates of 3791 µmol g−1 h−1 (with sacrificial reagent) and 923 µmol g−1 h−1 (without sacrificial reagent) from water and oxygen under visible light irradiation. This work demonstrates that pyrene‐4,5,9,10‐tetraone molecule could be introduced into PAF materials to construct efficient organic semiconductor photocatalysts for H2O2 production.
