Disclosed is a modified photocatalyst sol comprising a liquid medium having dispersed therein particles of a modified photocatalyst, wherein the modified photocatalyst particles are prepared by subjecting particles of a photocatalyst to a modification treatment with at least one modifier compound selected from the group consisting of different compounds each of which independently comprises at least one structural unit selected from the group consisting of a monooxydiorganosilane unit, a dioxyorganosilane unit and a difluoromethylene unit, and wherein the modified photocatalyst particles have a specific volume mean particle diameter. Also disclosed is a modified photocatalyst composition comprising the modified photocatalyst sol and a functional substance. Also disclosed are a film formed using the above-mentioned modified photocatalyst sol or modified photocatalyst composition, a functional composite comprising the film and a substrate covered with the film, and a shaped article produced by shaping the above-mentioned modified photocatalyst composition.
L'invention porte sur un sol photocatalyseur modifié comprenant un milieu liquide dans lequel sont dispersées des particules de photocatalyseur modifiées. Ces particules sont celles obtenues par modification avec au moins un composé modificateur sélectionné parmi des composés possédant chacun au moins un type d'unités structurales sélectionnées parmi des unités monooxydiorganosilane, des unités dioxyorganosilane et des unités difluorométhylène et qui ont un diamètre de particule moyen spécifique. L'invention porte également sur une composition de catalyseur modifiée comprenant le sol photocatalyseur modifié et une substance fonctionnelle. L'invention porte, en outre, sur un film obtenu à partir du sol photocatalyseur modifié ou de la composition de photocatalyseur modifiée, un composite fonctionnel comprenant un substrat recouvert du film et un objet moulé.
