▎ 摘  要

NOVELTY - Method for preparing graphene-based cerium-based nano composite material involves placing the graphite oxide in deionized water, ultrasonically dispersing uniformly to obtain the graphite oxide water solution, adding ceric ammonium nitrate to the graphite oxide water solution, stirring uniformly, adding cadmium nitrate and sodium sulfide, continuously stirring, fully mixing the system uniformly, and adjusting the pH to obtain the mixed reaction system, carrying out hydrothermal reaction for the mixed reaction system, filtering, washing and drying, grinding to obtain the product. USE - The method is used for preparing graphene-based cerium-based nano composite material which is used to degrade ciprofloxacin in water under visible light (all claimed). ADVANTAGE - The method has excellent synergistic effect between the three components of ceric ammonium nitrate, cadmium nitrate and sodium sulfide, and increases the photocatalytic performance of the composite material.
