▎ 摘　　要

NOVELTY - Preparation of composite catalyst of graphene oxide (GO) and cerium-based metal-organic frameworks (MOFs) involves (S1) mixing graphene oxide with ceric ammonium nitrate uniformly, (S2) dripping the uniformly mixed solution into a terephthalic acid solution, stirring while heating, and centrifuging to obtain white precipitate after the reaction, and (S3) washing the white precipitate with dimethyl formamide (DMF) and ethanol, and drying the washed product. USE - Preparation of composite catalyst of graphene oxide and cerium-based metal-organic framework for adsorbing and degrading antibiotics e.g. sulfamethoxazole in sulfamethoxazole-containing wastewater (all claimed). ADVANTAGE - The method provides composite catalyst having improved kinetic performance due to its kinetic constant of more than 3 times that of UIO-66(Ce) and GO before composite, and ensures degradation of 78% of sulfamethoxazole within 240 minutes, thus ensuring effective removal of antibiotics in water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage method of the composite catalyst, which involves adding the composite catalyst into wastewater containing sulfamethoxazole, and adsorbing and degrading sulfamethoxazole under visible light conditions.
