Abstract

L'invention concerne une composition photoactive comprenant 0,1 à 40 % en poids d'un photocatalyseur présent dans une phase pulvérulente ou dans une phase en solution, ou d'un photocatalyseur en alcoxyde de métal; et 0,1 à 30 % en poids de scories en poudre, l'équilibre étant apporté par un solvant. Elle concerne également une méthode de préparation de la composition. Lorsqu'un revêtement interne est réalisé au moyen de la composition photoactive de l'invention, son activité peut se révéler même sans irradiation additionnelle de lumière, et une matière organique peut être adsorbée et décomposée avec grande efficacité rien qu'avec une source lumineuse très faible, par combinaison du résultat de l'adsorption de scories et du résultat de la décomposition d'un photocatalyseur. Etant donné que la composition photoactive ne se trouve pas dans une phase pulvérulente mais dans un état colloïdal liquide, elle peut s'utiliser efficacement comme agent de revêtement pour le traitement en surface d'un quelconque matériau, ou comme agent d'addition intervenant dans le processus de préparation de matériaux industriels ou de produits transformés.
