A green, rapid and facile method for synthesis of pure rutile TiO₂ has been developed. Rutile TiO₂ of high purity was synthesized by controlled hydrolysis of TiCl₃ in aqueous medium at room temperature. Addition of nitric acid to TiCl₃ greatly increased the rate of TiCl₃ hydrolysis, crystallization and surface area of the prepared TiO₂ powder. The phase obtained in this way was identified by X-ray diffraction. TiO₂ synthesized by this method showed a unique flower-like assembly of nanotubes, very high surface area and high photocatalytic activity under visible light irradiation.
