▎ 摘 要
NOVELTY - Preparing graphene-based zinc doped bismuth molybdate catalyst, comprises placing the graphite oxide in the solvent 1, ultrasonically dispersing uniformly to obtain the graphene oxide solution, adding the bismuth nitrate and the sodium molybdate into the solvent 2 to stir uniformly to obtain the solution 3, dropping the solution 3 into the graphite oxide dilute solution, stirring uniformly, adding zinc solution, stirring again, fully mixing the system uniformly, adjusting the pH to obtain the mixed solution, stirring the mixed solution uniformly and performing solvent thermal reaction, after filtering, washing and drying, and grinding. USE - The catalyst is useful for photo-catalytically degrading ciprofloxacin (claimed). ADVANTAGE - The method is simple, the raw materials are cheap and easy to obtain, is environmentally friendly, and exhibits extremely high photocatalytic degradation efficiency in the degradation of ciprofloxacin in water.
