NOVELTY - Catalytic decomposition of antibiotics by Z-type catalyst under visible light involves dissolving sodium tungstate dihydrate and inorganic salts in ultrasonically dispersed graphene oxide solution, adding acidic solution, adjusting pH value to 2, transferring solution to reaction vessel, reacting, cooling to room temperature, adding organic matter and concentrated hydrochloric acid, reacting under high pressure to collect synthesized carbon nanodots, neutralizing carbon nanodots solution with basic substance to neutrality, carrying out dialysis treatment, mixing tungsten trioxide/reduced graphene oxide and carbon nanodots, reacting, mixing tungsten trioxide/reduced graphene oxide/carbon nanodots and antibiotic solution, and reacting under visible light for a certain period of time. USE - Catalytic decomposition of antibiotics by Z-type catalyst under visible light. ADVANTAGE - The method enables simple and economical catalytic decomposition of antibiotics by Z-type catalyst under visible light with improved photocatalytic performance, and photocatalytic stability.
