Pyrene‐4,5,9,10‐Tetraone‐Based Porous Aromatic Frameworks for Photocatalytic Production of Hydrogen Peroxide

Abstract Three pyrene‐4,5,9,10‐tetraone‐based porous aromatic frameworks (PT‐PAFs) are synthesized and their photocatalytic properties for H 2 O 2 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 H 2 O 2 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 H 2 O 2 production.
