METHOD FOR PRODUCTION OF NANOSIZE PARTICLES OF TITANIUM DIOXIDE Russian patent published in 2009 - IPC C01G23/53

Abstract RU 2349549 C2

FIELD: nanotechnologies.

SUBSTANCE: invention is related to methods for production of nanosize particles of titanium dioxide, which may be used as photocatalysts, light sensitive materials of sun batteries, photo luminophors, as cathode materials of chemical current sources. Method for production of such particles of titanium dioxide includes hydrolysis of water solution that contains titanium ions, in presence of acid during heating. Water solution containing titanium ions is produced by dissolution of titanium hydride or metal titanium in 37% hydrochloric or 96% sulfuric acid dissolved with water, accordingly, as 1:2 or 1:3.4, to obtain ratio of Ti⁺³ : Cl^-, equal to 1:6, or Ti⁺³ : SO₄ ^2-, equal to 1:3. Hydrolysis may be performed in presence of nickel chloride or cobalt chloride.

EFFECT: invention makes it possible to simplify production of nanosize particles of titanium dioxide of different shape - in the form of nanobars, nanorods, nanoneedles, without negative effect at environment.
