▎ 摘  要

NOVELTY - Preparing graphene-based photocatalytic material, comprises (i) preparing bismuth-graphene composite by using bismuth chloride and liquid polyacrylonitrile as raw materials, (ii) mixing the step (i) bismuth-graphene composite with bismuth iodide and chloroplatinic acid to obtain preform, and (iii) formulating preform into suspension, then adding alpha -naphthylamine monomer, and carrying out polymerization reaction to obtain aforementioned graphene-based photocatalytic material. Bismuth iodide obtained by hydrothermal reaction using potassium iodide solution and bismuth salt as raw materials; and preform is heat-treated with mixed gas of oxygen and nitrogen thus metal nitrogen oxides is formed on the surface of the preform. USE - The method is useful for preparing graphene-based photocatalytic material. ADVANTAGE - The photocatalytic material: has excellent photocatalytic degradation effects on pollutants in air and aqueous solutions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-based photocatalytic material, obtained by above mentioned method.
