Photocatalytic material, method for preparing the photocatalytic material and photocatalytic air screen filter for epidemic prevention

Abstract

A photocatalytic material includes activated carbon, titanium dioxide, zinc oxide, graphene, tourmaline powders, a nano-copper solution, carvacrol and deionized water. The photocatalytic material is prepared by mixing the activated carbon, the titanium dioxide, the zinc oxide, the graphene, the tourmaline powders, the nano-copper solution, the carvacrol and the deionized water for a period ranging from 1 to 12 hours. A photocatalytic air screen filter for epidemic prevention includes a substrate and the photocatalytic material. The photocatalytic material is applied on a surface of the substrate, and the photocatalytic material is dried and cured. An amount of the material loaded on the surface of the substrate is in a range of 0.1 to 100 mg/cm2.
