The application of titanium dioxide in the field of photocatalyst was limited. Since, it was activated only a small extend under UV irradiation. While the metal doped TiO2 had shown better photocatalytic activity. The work designed to prepare tin titanate (SnTiO3) by a simple co-precipitation peroxide method. The ratio of the starting compounds, Sn and Ti was taken as 1:1. The prepared powder was calcined at 850°C. The stoichiometric ratio of the synthesized titanate was measured by using AAS. The synthesized titanate had analyzed by X- ray diffraction (XRD). FTIR was taken for confirming the bonding characteristics of Sn-O and O-Ti-O. Thermo gravimetric analysis (TGA) was used to analyze the decomposition temperature. The optical and photocatalytic activity of the synthesized powder was evaluated by Lead carbonate test by using Hunter lab color difference meter. Color difference was determined using a white medium and strength had been determined using black medium. The prepared SnTiO3 powder had exhibited better photocatalytic activity.
