NOVELTY - Preparation of graphene-modified air purification material, involves (1) adding a rare earth mesoporous oxide to the graphene oxide dispersion, stirring to obtain a uniformly dispersed mixed liquid, (2) stirring, slowly adding cyclodextrin to the mixture obtained in step (1), adding, and reacting at 20-60 degrees C for 2-4 hours, and (3) adding titanium dioxide to the reaction liquid of the step (2), stirring the reaction at 70-120 degrees C to obtain a colloid, and calcining the obtained colloid. USE - Preparation of graphene-modified air purification material (claimed). ADVANTAGE - The synergistic action of adsorption and photocatalysis is utilized to purify the air. The air purification efficiency is improved.
