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 2-propanol 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.
