Abstract

The invention discloses a preparation method of a TiO2/diatomite composite material. The composite material prepared by smearing self-made TiO2 nano material and diatomite onto a flame-retardant nonwoven fabric is simple, practical and easy to recover and also solves the problem that the composite photocatalyst in the prior art is low in capacity for degrading organic contaminants. The preparation method is not only simple and easy in operation; moreover, the product is stable in quality and high in market application and popularization value.

Description

technical field [0001] The invention relates to the technical field of catalytic materials, more specifically to a TiO 2 / The preparation method of diatomite composite material. Background technique [0002] Due to its unique ordered microporous structure, high porosity, large pore volume, light weight, large specific surface area, strong adsorption and good activity, diatomite is often used as an adsorbent for harmful pollutants to improve indoor environment. However, there is a certain degree of saturation in the adsorption of diatomite to harmful pollutants. When the maximum adsorption capacity of diatomite is reached, the harmful substances will not be eliminated. [0003] At present, it is mainly to combine diatomite with photocatalytic materials (TiO 2 ) compound to improve the efficiency of degrading harmful pollutants to achieve the purpose of purification. However, suspended TiO 2 In practical applications, photocatalysts have problems such as easy aggregation,...
