Title (EN) TITANATE / TITANIA COMPOSITE NANOPARTICLE
(FR) NANOPARTICULE COMPOSITE À BASE DE TITANATE/DIOXYDE DE TITANE
Abstract: front page image
(EN)The present invention relates to a photocatalytically active nanoparticulate material. A nanoparticle of the invention is a composite nanoparticle having two crystalline phases: hydrogen titanate and titania, which are uniformly mixed in the nanoparticle. The invention also relates to forming a nanoparticulate composite material by heating a basic titania sol under solvothermal conditions.
(FR)La présente invention concerne un matériau nanoparticulaire à activité photocatalytique. Une nanoparticule selon l'invention est une nanoparticule composite possédant deux phases cristallines : du titanate d'hydrogène et du dioxyde de titane, qui sont mélangés de manière homogène dans la nanoparticule. L'invention concerne également la formation d'un matériau composite nanoparticulaire par le chauffage d'un sol basique de dioxyde de titane dans des conditions solvothermiques.
