摘要

The invention relates to system having colloidal dispersion -paste with photocatalytic properties for purification of air from harmful volatile organic compounds, volatile inorganic compounds and microorganisms, and to a method for preparation of porous materials with a layer of photocatalytic paste. The invention finds use in removal of volatile organic compounds, volatile inorganic compounds and pathogenic microorganisms suspended in air, such as bacteria, fungi, fungi spores, viruses. The invention finds use particularly in deodorisation devices and devices for purification of air streams emitted in wastewater management facilities. The paste comprises from 1 to 60% by wt. (per the whole system) of TiO2 particles having grain sizes from 10-9 to 10-5 m and structure of anatase, rutile or their mixture; a non-ionic surfactant in the amount of 1 to 20% by wt.; a polymer in the amount of 1 to 20% by wt. having molecular mass of 200 to 20000; a solvent in the amount of 40 to 95% by wt.; as well as a pH stabiliser operating in the range from 5 to 9 in the amount of 1 to 5% by wt. and a viscosity stabiliser in the range from 0.001 to 40 Pa.s at a temperature of 25°C.
