▎ 摘　　要

NOVELTY - The preparation of composite material involves dispersing silver source, graphene oxide and polyvinylpyrrolidone in water to obtain dispersion, performing redox reaction at 100 degrees C to obtain silver/reduced graphene oxide composite material, adding platinum source, and performing galvanic conversion reaction at 50-200 degrees C. USE - Preparation of silver loaded silver chloride/platinum/reduced graphene oxide composite material for degrading organic dye such as methyl orange, rhodamine B and methylene blue (claimed). ADVANTAGE - The method enables preparation of silver loaded silver chloride/platinum/reduced graphene oxide composite material using simple one-pot two-step reaction process, with reduced energy consumption, reduced normal pressure reaction temperature, reduced cost, high catalysis efficiency, and is suitable for large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of composite material as photocatalyst for catalytic degradation of organic dyes.
