Preparation of TiO2 Photocatalysts by Multi-gelation and Their Photocatalytic Reactivity for the Degradation of 2-Propanol

TiO2 photocatalysts, prepared by a multi-gelation method, showed higher photocatalytic activity for the degradation of 2propanol diluted in water. This multi-gelation method showed a good performance in controlling the parameters viz. particle size, surface area, crystallinity as well as anatase and rutile phase composition, which are responsible for the higher activity of these photocatalysts.
