Zinc titanate powder was synthesizd by an organic free co-precipitation peroxide technique. Zinc chloride and titanium (IV) isopropoxide were used as the primary material with the ratio of Zn:Ti was 1:1 and the later compound was prepared by mixing titanium chloride with isopropanol. The stoichiometric ratio of the synthesized zinc titanate was measured by using AAS. The synthesized powder was calcined at 800°C for 3 hours using the X-ray diffraction and the calcined zinc titanate powder crystalline phase formation was found to be cubic. FTIR was used for studying the bonding characteristics of ZnO and TiO2. Disintegration temperature was analyzed by means of Thermogravimetric analysis. The photocatalytic activity was measured based on the degradation of methyl orange in aqueous solution in the presence of metallic sodium. The results showed that ZnTiO3 particle exhibited good photocatalytic activity under visible range radiation.
