FIELD: chemistry.
SUBSTANCE: method of obtaining a modified photocatalyst based on titanium dioxide for the photocatalytic air purification, consisting in the fact that the nanocrystalline powder of titanium dioxide in the anatase modification with a specific surface area above 300 m2/g is subjected to treatment with an aqueous solution of the fluorine-containing agent in a molar ratio of fluorinated agent and titanium dioxide of 0.09-0.11:1 with the subsequent processing of the slurry with a mineral acid to achieve pH=4-4.5.
EFFECT: obtaining a highly active photocatalyst, allowing to reduce the time required in the purification of air from volatile organic compounds and intermediates of incomplete oxidation in the course of photocatalysis, 2 or more times by increasing the speed of photocatalytic oxidation.
