▎ 摘　　要

NOVELTY - A metal-organic framework/graphene quantum dot nanocomposite photocatalyst is prepared by preparing metal-organic framework material using terephthalic acid and chromium(III) nitrate nonahydrate via hydrothermal method, preparing graphene quantum dot solution using glucose hydrothermal method at 180-200degrees Celsius for 3-4 hours, mixing with metal-organic framework, stirring at room temperature for 4-6 hours, and post-processing. USE - Method for preparing metal-organic framework/graphene quantum dot nanocomposite photocatalyst. ADVANTAGE - The method has mild conditions, good product purity and is suitable for industrialization.
