NOVELTY - Preparation of metal organic framework (ZIF-8)/reduced graphene oxide (rGO) composite photocatalyst involves (s1) mixing zinc nitrate hexahydrate solution and dimethylimidazole solution, continuously stirring and reacting, filtering, washing, and drying to obtain ZIF-8, and (s2) adding a graphene oxide (GO) aqueous solution to an ethanol dispersion of ZIF-8, stirring for 20 hours, heat-reacting, and cooling after the reaction. USE - Preparation of metal organic framework (ZIF-8)/reduced graphene oxide composite photocatalyst for photocatalytic production of hydrogen peroxide and photocatalytic degradation of antibiotic e.g. ciprofloxacin and/or tetracycline (all claimed). ADVANTAGE - The method is simple, stable and economical, and provides photocatalyst for efficient production of hydrogen peroxide and degradation of pollutants.
