Abstract

Using[(n-C₄H₉)₄N]₄[W₁₀O₃₂], AgNO₃ and 4,4'-bipyridine (BPY) as raw materials, the first photosensitive H₂[Ag₂(W₁₀O₃₂)(BPY)₄] material was synthesized by hydrothermal method (named AgW-BPY), and its structure, optical properties and performance of heterogeneous photocatalytic oxidation of cyclohexane were studied. The results showed that the covalent bond between the photosensitivity[W₁₀O₃₂]^4- polyacid anion and the MOF framework made[W₁₀O₃₂]^4- polyacid anion difficult to dissolve from the MOF framework, and the heterogeneous immobilization of anions W₁₀O₃₂^4- polyacid was successfully realized; AgW-BPY had a band gap value of 2.30 eV, which had the potential as a photocatalyst; under visible light irradiation at room temperature, AgW-BPY had good photocatalytic activity for molecular oxygen oxidize cyclohexane to cyclohexanone and cyclohexan, the conversion efficiency was 76.1%,and the conversion rate was still 74.5% after 3 cycles of experiments.
