▎ 摘  要

NOVELTY - A ternary visible light photocatalytic nanocomposite material is prepared by taking pyrene and nitric acid, reacting to obtain trinitropyrene, adding water and phosphorus source, adjusting pH value to 10-11, performing hydrothermal reaction at 180degrees Celsius to obtain phosphorus-doped graphene quantum dot, preparing into an aqueous solution, mixing with titania nanoparticles, silver nitrate and potassium iodide, filtering, and drying. USE - Method for preparing ternary visible light photocatalytic nanocomposite material. ADVANTAGE - The product has catalytic efficiency of 99.35% in 10 minutes after putting into the methyl orange solution under the irradiation of visible light exhibiting excellent catalytic performance.
