The production of hydrogen peroxide (H2O2) by combining photocatalytic oxygen (O2) reduction with water (H2O) oxidation is a satisfactory substitute for the industrial anthraquinone process. But efficiency H2O2 generation still low, especially in heterogeneous reactions, owing to poor mass transfer and weak H2O oxidation. Hereby, porous organic framework (BPYTEA-POF) hexagonal hollow nanotube structure was synthesized through 5,5′-dibromo-2,2′-bipyridine (BPY) reacting tris(4-ethynylphenyl)amine (TEA) Sonogashira coupling reaction without template, which contains 2,2′-bipyridine active site. BPYTEA-POF morphology hierarchical wall beneficial and/or diffusion substrate via siphonic effect; meanwhile, it benefits exposure catalytic site, boosts contact O2 site rapidly dissociates generated H2O2, thus improving efficiency. At same time, moiety capable effectually weakening O–H bonds promoting produce proton (H+); then, produced H+ were used efficient under additive-free condition. definite specific sites enhance initial rate up 3446 μmol gcat–1 h–1, condition visible-light irradiation (λ ≥ 400 nm) any additional additive.
