▎ 摘　　要

NOVELTY - Graphene oxide is dispersed in a solvent to obtain a graphene oxide colloid with a concentration of 0.01-10 mg/mL. A one-dimensional photocatalyst is dispersed in a solvent to obtain a photocatalyst suspension with a concentration of 0.01-1000 mg/mL. Both solutions are mixed and stirred in a mass ratio of 100:1-1:100, put into an open container, irradiated for 0.5-1000 hours, reacted, centrifugally separated, and dried to obtain a photocatalyst/graphene one-dimensional core-shell composite structure. USE - Preparation of photocatalyst/graphene one-dimensional core-shell composite structure by photocatalysis. ADVANTAGE - The method enables environmentally-friendly, quick, convenient, economical, efficient and simple preparation of highly pure photocatalyst/graphene product without using any organic surfactant, complex separation and purification process, and hazardous substances, with excellent reproducibility. Since reaction is carried out under visible light or UV light, natural light is adequate.
