FIELD: chemistry.
SUBSTANCE: this invention relates to sol of catalytically-active titanium oxide, coat composition with said sol, parts with said coat and method of coating. Sol of catalytically-active titanium oxide contains titanium oxide, silver in amount of 0.1-5 wt % in the form of Ag2O/TiO2, copper with its fraction expressed as CuO/Ag2O relative to amount of silver equals 1-30 wt %, and quaternary ammonium hydroxide. Coat composition represents said sol dispersed in binder. Proposed method consists in applying said coat on substrate surface.
EFFECT: stable sol with photocatalytic activity.
