▎ 摘　　要

NOVELTY - A copper indium disulfide quantum dot/reduced graphene oxide composite photocatalytic material is obtained by dissolving copper indium disulfide in methanol, adding graphene oxide powder, pouring the system into a high-pressure reactor, heating at 200 degrees C in an oven, continuously reacting for 1 hour, removing, naturally cooling, centrifuging the solution, washing thrice using deionized water and methanol, and drying in a dry box. Optimal degradation effect of copper indium disulfide quantum dot/reduced graphene oxide composite photocatalytic material is obtained by controlling indium acetate in preparation of copper indium disuldide, molar ratio of cuprous iodide to dodecyl mercaptan, heating temperature of oil bath, cold water temperature and time, and mass ratio of graphite oxide to copper indium disulfide. USE - Copper indium disulfide quantum dot/reduced graphene oxide composite photocatalytic material is used for degrading tetracycline hydrochloride in antibiotic wastewater under visible light (claimed). ADVANTAGE - The copper indium disulfide quantum dot/reduced graphene oxide composite photocatalytic material efficiently degrades tetracycline hydrochloride in antibiotic wastewater by simple method without affecting the environment.
