Abstract

TiO₂ reported in all litterateurs with three phases anatase, rutile and brookite which variance in activities and most of chemical properties. The variance in properties represent one of the best strategy to enhance the activities. Thus in this work TiO₂ were prepared with different crystal mixture from TiOSO₄/H2O₂ by change the values of pH for the solution (3, 8, 11 and 14).  the synthesized TiO₂ were characterized by Raman spectroscopy and X-ray diffraction and that shown different phases for the product. The results of analysis show that Anatase prefer acid solution which change to rutile and brookite or forming amorphous TiO₂ with change the pH towards basic solution.

Keywords: TiOSO4/H2O2, anatase, pH, Raman/XRD, rutile
