▎ 摘　　要

NOVELTY - Preparing high performance bismuth vanadate-titanium dioxide- reduced graphene oxide (BiVO4/TiO2/RGO) nano composite material comprises dissolving the bismuth source in the acid, dissolving the vanadium source in the alkali, mixing and stirring uniformly to obtain the mixed metal salt solution, adding graphite oxide in de-ionized water, ultrasonically dispersing uniformly, obtaining graphite oxide aqueous solution, dispersing the obtained mixed metal salt solution in the graphene oxide solution and stirring uniformly, adding titanium source, adjusting pH, stirring, heating reaction, filtering, washing and drying after cooling and grinding. USE - The material is useful in the degradation of ciprofloxacin (claimed). ADVANTAGE - The material has good synergistic effect between the graphene and BiVO4/TiO2 components, so as to increase the photo-catalytic degradation of the composite material ciprofloxacin performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) high performance bismuth vanadate-titanium dioxide- reduced graphene oxide nano composite material prepared as mentioned above; and (2) degradation of ciprofloxacin comprising using nano composite material adding 10 mg of the product to every 10 mg/l aqueous solution of ciprofloxacin under visible light, adjusting the pH to 6, where the degradation rate of ciprofloxacin can reach 80% within 150 minutes.
