▎ 摘　　要

NOVELTY - Preparing high performance bismuth oxyhalide/graphene nano-composite material comprises adding iron salt in bismuth salt, chloride solution, stirring uniformly to obtain mixed metal salt solution, where the mol ratio of the bismuth salt and the solute in the chloride salt is 1:1, thermally reacting the mixed metal salt solution at 160 degrees C for 12 hours, filtering, washing, drying and grinding to obtain iron doped bismuth oxychloride, ultrasonically dispersing the graphite oxide in the solvent uniformly to obtain the graphite oxide solution, dispersing the iron-doped bismuth oxychloride in the graphene oxide solution, stirring uniformly to obtain the mixed reaction system, performing solvent thermal reaction, filtering, washing, drying, grinding to obtain the bismuth oxyhalide/graphene nano composite material. USE - The material is useful in degrading ciprofloxacin in water under visible light (claimed). ADVANTAGE - The material: has good synergistic effect between each component of graphene and iron/bismuth oxychloride (Fe/BiOCl), so as to increase the performance of the photocatalytic material for degrading ciprofloxacin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for iron-doped bismuth oxychloride/graphene nanocomposite material, prepared by above method.
