The invention discloses a preparation method of a sulfide quantum dot modified graphene/zinc oxide nanoparticle photocatalytic material, which comprises the following steps: dispersing 5-10 g of graphene/zinc oxide nano-microspheres in 50-100 mL of absolute ethanol, and adding 20-45 mL of sulfide quantum dot solution while stirring; and evaporating the solution to dryness, and grinding to obtain the sulfide quantum dot modified graphene/zinc oxide nano microsphere photocatalytic material. The method is beneficial to widening the spectral response range of the graphene/zinc oxide nano catalytic material, improving the optical quantum yield and catalytic activity, promoting the recovery of the graphene/zinc oxide nano catalytic material in sewage treatment, and solving the problems of narrow spectral response range, low photocatalytic efficiency, difficult recovery and the like of the graphene/zinc oxide nano catalytic material in practical application. |
