METHOD OF MANUFACTURING MODIFIED TITANIUM (IV) OXIDE NANOPARTICLES AND MODIFIED TITANIUM (IV) OXIDE NANOPARTICLES

摘要

A method of manufacturing modified titanium (IV) oxide nanoparticles consists in that, in the I phase the mixture of titanium ion precursor and aqueous hydrolysis catalyst solution is subjected to sonication, then in the II phase an organic substance modifying the structure of nanoparticles selected from the group consisting of glutathione, mannose or galactose is introduced into it and the whole subjected to elevated temperature and increased pressure in the microwave field in a pressure microwave reactor or in a pressure reactor with conventional heating, and then in the III phase the obtained suspension is subjected to centrifugation and/or filtration and washing, and the obtained precipitate is dried and ground. Titanium (IV) oxide nanoparticles whose surface is coated with at least one substance selected from the group consisting of glutathione, mannose or galactose.
