Title
(EN) MODIFIED INDUSTRIAL INORGANIC PIGMENTS WITH THE SURFACE DECORATED WITH ION-MADE CLUSTERS OF D-TYPE TRANSITIONAL METALS, PROCESS FOR OBTAINING THEREOF, COMPOSITIONS CONTAINING THEM AND USES THEREOF
(FR) PIGMENTS INORGANIQUES INDUSTRIELS MODIFIÉS AYANT LA SURFACE DÉCORÉE AVEC DES AMAS D'IONS DE MÉTAUX DE TRANSITION DE TYPE D, LEUR PROCÉDÉ D'OBTENTION, COMPOSITIONS LES CONTENANT ET LEURS UTILISATIONS
Abstract
(EN) The present invention relates to modified industrial inorganic pigments based on semiconductor metal oxides selected from TiO2, the crystalline form of anatase or rutile, or ZnO which have a micrometric dimension and a surface decorated with clusters formed of d-type transition metal ions, to a process for obtaining thereof, to the compositions comprising thereof and to their multiple uses. The product disclosed by the present invention has as a characteristic the displacement of its photocatalytic response from the UV-A domain to the visible spectrum, it exhibiting bactericidal activity both in the visible spectrum and in the dark. Modified industrial inorganic pigments based on semiconductor metal oxides or modified semiconductor metal oxides disclosed by the present invention may be incorporated into various compositions, compositions that will have photocatalytic activity in the visible spectrum and catalytic activity in the dark.
(FR) La présente invention concerne des pigments inorganiques industriels modifiés à base d'oxydes métalliques semi-conducteurs choisis parmi TiO2, la forme cristalline d'anatase ou de rutile, ou ZnO qui ont une dimension micrométrique et une surface décorée avec des amas formés d'ions de métal de transition de type d, leur procédé d'obtention, les compositions les comprenant et leurs utilisations multiples. Le produit de la présente invention a pour caractéristique le déplacement de sa réponse photocatalytique du domaine UV-A au spectre visible, le produit présentant une activité bactéricide à la fois dans le spectre visible et dans l'obscurité. Des pigments inorganiques industriels modifiés à base d'oxydes métalliques semi-conducteurs ou d'oxydes métalliques semi-conducteurs modifiés selon la présente invention peuvent être incorporés dans diverses compositions, des compositions qui présenteront une activité photocatalytique dans le spectre visible et une activité catalytique dans l'obscurité.
