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.
