▎ 摘　　要

NOVELTY - Preparing halide perovskite-graphene-platinum composite material comprises adding composite material into N,N-dimethylformamide solution together by precursor AX, PbX2and graphene oxide, obtaining APbX3-GO photocatalytic material by anti-solvent method, catalytically reducing graphene oxide to graphene by light irradiation, and loading noble metal platinum on surface of catalyst. USE - The method is useful for preparing halide perovskite-graphene-platinum composite material as composite photocatalyst for photocatalytic anaerobic selective oxidation of aromatic alcohol coupled hydrogen production reaction under visible light irradiation for enhancing performance of hydrogen production and aromatic aldehyde production (claimed). ADVANTAGE - The method: is simple, and convenient; and has high catalytic efficacy. The material: has high photocatalytic performance, which can strengthen performance of hydrogen production and aromatic aldehyde production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for halide perovskite-graphene-platinum composite material, prepared by above method.
