LETTER TO THE EDITOR

Anatase TiO2 hydrosol was prepared by hydrolyzation of tetrabutyl titanate followed by acidic peptization of the precipitate under 70 °C. The method was highly simplified and the growth of TiO2 nanocrystallites that bothered traditional preparations was avoided. The photocatalytic activity of the hydrosol was confirmed through the photocatalytic degradation of methyl blue dye under visible light irradiation.
