Abstract

L'invention porte sur un nouveau procédé pour la fabrication d'une dispersion de dioxyde de titane par mélange de deux dispersions de dioxyde de titane différentes synthétisées par un procédé solvothermique et un procédé d'hydrolyse. La dispersion de dioxyde de titane a une pluralité de particules de dioxyde de titane pratiquement uniformément dispersées dans celle-ci et peut être mélangée pour fournir une concentration élevée de dioxyde de titane avec une structure cristalline de type anatase pour fournir le niveau souhaité d'activité photocatalytique. La présente invention permet également la fabrication de dispersions de dioxyde de titane transparentes. La solution peut être utilisée pour diverses applications de décontamination et de production d'énergie propre.
