Title (EN) TITANIUM-DIOXIDE COMPOSITIONS
(FR) COMPOSITIONS DE DIOXYDE DE TITANE
Abstract:
(EN) The present invention provides a titanium dioxide composition comprising nano- sized particles said particles being characterized by: (i) being comprised essentially of anatase; (ii) having a mean size, according to XRD, of Lx, a mean size, according to SEM, of Ls, and a mean size distribution in suspension of Ln, wherein the ratio (Rs) of Ls/Lx is in the range of between 1.2 and 10, or wherein the ratio (RN ) of Ln/Lx is in the range of between 1.2 and 12, or both; and at least one of: (Ni) demonstrating photo catalytic activity (PCA (vis)) which is greater than 2.5; and (iv) demonstrating specific photo catalytic activity (SPCA(vis)) in the range greater than 0.22.
(FR) La présente invention a pour objet une composition de dioxyde de titane comprenant des nanoparticules, lesdites particules étant caractérisées : (i) en ce qu'elles sont composées essentiellement d'anatase; (ii) en ce qu'elles ont une taille moyenne, conformément à la XRD, de Lx, une taille moyenne, conformément à la SEM, de Ls, et une distribution de taille moyenne en suspension de Ln, le rapport (Rs) de Ls/Lx étant compris dans la gamme entre 1,2 et 10, ou le rapport (RN) de Ln/Lx étant compris dans la gamme entre 1,2 et 12, ou les deux; et (Ni) en ce qu'elles présentent une activité photocatalytique (PCA (vis)) qui est supérieure à 2,5; et/ou (iv) en ce qu'elles présentent une activité photocatalytique spécifique (SPCA(vis)) dans la gamme supérieure à 0,22.
