Abstract
L'invention entend proposer de réduire le taux de recombinaison d'électrons/de trous dans un photocatalyseur. L'invention concerne alors des particules cristallines plates collées à des particules cristallines en trois dimensions. L'une des deux sortes de particules montre une catalyse en cas d'irradiation avec une lumière visible ou de l'ultraviolet. Les deux types de particules possèdent la même taille moyenne. Le photocatalyseur après application et séchage possède une porosité inférieure ou égale à 50%.
