Mixed metal oxides are synthesized from corresponding oxides and are used as pigments in paints which constitutes the Nanoformulated paints. The behavioural studies of these Nanoformulated paints are investigated in various aspects. The studies show better hiding power and enhanced glossiness. Nanoformulated paint coatings are done on mild steel plate and the coatings were tested in corrosion atmosphere. The results of corrosion tests were compared with commercially available red and white paint. Also the corrosion behaviour was studied for TiO2 and Fe2O3 formulated paint along with TiO2.Fe2O3. The mixed metal oxides TiO2.Fe2O3 shows better corrosion inhibition efficiency. The particle size of the prepared oxide nanoparticles are confirmed with SEM. The structural and functional purity of the oxides were confirmed with XRD and FTIR respectively. Furthermore the studies were extended by evaluating the photocatalytic behaviour of the prepared oxides. It is found that upon UV irradiation on the dye the photocatalytic degradation was significantly increased. This studies confirms that incorporation of these nanoparticles in paints enhances the photocatalytic activity which results in the reduction of volatile organic compounds
