▎ 摘  要

NOVELTY - A zirconium porphyrin-based metal organic framework (MOF)-graphene composite photocatalyst generating singlet oxygen is prepared by dissolving precursor 5,10,15,20-tetracarboxylphenylporphyrin (H2TCPP), zirconium(IV) oxychloride octahydrate and benzoic acid in dimethylformamide (DMF) solvent, transferring solution into high pressure reaction kettle, carrying out solvothermal reaction at 120 degrees C for 5 hours, centrifuging, washing, drying to obtain zirconium porphyrin MOF nanoparticle, uniformly dispersing graphene oxide and zirconium porphyrin MOF nanoparticle in ethanol under the action of ultrasonic cell crushing instrument, transferring dispersion liquid into high pressure reaction kettle, performing composite reaction at 120 degrees C, centrifuging, washing and drying. USE - The method is used for preparing zirconium porphyrin-based metal organic framework-graphene composite photocatalyst generating singlet oxygen for eliminating antibiotic pollutant, specifically degradation of quinolone antibiotics under irradiation of simulated solar light (claimed).
