The homogeneous hydrolysis method was proposed to synthesize nanoscale TiO2 mixed crystal. It is remarkable that the content of rutile crystal phase in TiO2 mixed crystal was controllable by the addition of toluene-p-sulfonic acid. The relationship between toluene-p-sulfonic acid and rutile phase of TiO2 was presented. TiO2 was pure anatase crystallite without the addition of toluene-p-sulfonic acid. The sample with 0.2 addition ratio of toluene-p-sulfonic acid was studied. The properties of a TiO2 sample prepared are that the size of nano-crystallite was 19.5 nm for rutile, and 13.5 nm for anatase, the specific surface area was 72.7 m(2)/g, and the energy of band gap was 2.83 eV.
