(FR) NANOPARTICULES PHOTOACTIVES EN LUMIÈRE VISIBLE ET PROCÉDÉS DE PRÉPARATION DE CES DERNIÈRES
Abstract: front page image
(EN)A particle (1) is proposed with photoactivity under irradiation in the visible range of the electromagnetic spectrum comprising a core-particle (2) of titanium dioxide with an average diameter in the range of 3-300 nm; on the surface of said core-particle (2) nanoparticles with an average diameter in the range of 2-90 nm forming at least one metal nano-deposit (3) partially covering said surface; on the surface of said nanoparticles of at least one noble metal nano-deposit a layer containing crystalline titanium-suboxides (4) that preferably contact said core-particle (2) surface.
(FR)L'invention concerne une particule (1) ayant une photoactivité lors d'une exposition à un rayonnement dans la plage visible du spectre électromagnétique comprenant une particule-noyau (2) en dioxyde de titane ayant un diamètre moyen dans la plage de 3 à 300 nm ; sur la surface de ladite particule-noyau (2), des nanoparticules ayant un diamètre moyen dans la plage de 2 à 90 nm formant au moins un nano-dépôt de métal (3) recouvrant partiellement ladite surface ; sur la surface desdites nanoparticules d'au moins un nano-dépôt de métal noble, une couche contenant des sous-oxydes de titane cristallins (4) qui est de préférence en contact avec ladite surface de particule-noyau (2).
