METHOD OF PRODUCING HYDRATED TITANIUM DIOXIDE BASED PRECURSOR WITH NANO-SIZED PALLADIUM METAL PARTICLES FOR CATALYTICALLY ACTIVE COATING ON INERT CARRIER Russian patent published in 2016 - IPC B01J37/02 B01J21/06 B01J23/44 B22F9/24 B82Y30/00

Abstract RU 2576568 C2

FIELD: chemistry.

SUBSTANCE: invention relates to production of a precursor based on titanium dioxide for catalytically active coating on an inert carrier containing nano-sized metal particles of palladium. Colloidal solution of a siloxane-acrylate emulsion, while stirring, is mixed with a solution of tetrachloropalladic acid H₂PdCl₄ and under constant stirring are heated at a temperature of 75-80°C. Resulting solution is cooled followed by reduction of palladium from ionic form to metal in form of nanoparticles by adding a reducing solution of titanium(III) chloride in hydrochloric acid, followed by stirring resulting colloidal solution for a time sufficient for complete hydrolysis and polycondensation to form hydrated titanium dioxide TiO₂·nH₂O.

EFFECT: obtaining thermally stable oxide coating containing palladium nanoparticles, using said precursor.
