Abstract: TiO2 is used as photo catalyst because of its high oxidation power, stability and non toxicity.Cu-TiO2 nanocomposites was prepared by a adopting the solution impregnation method. After characterization for crystalline phase and particle size by XRD analysis, SEM analysis was carried out to seen morphology of samples, Surface area of TiO2 and Cu-TiO2 were analysed by BET. Both the prepared TiO2 and synthesized Cu-TiO2 nanocomposites were used as photo catalyst in the photo-degradation of methyl red. The Photo-degradation of methyl red in the presence of pure TiO2 and synthesized Cu-TiO2 was done. The Photo-degradation of methyl red were investigated at different condition of temperature, concentration and pH. The effective photo-degradation was found in case of methyl red in the presence of Cu-TiO2 as compared to pure TiO2 at different conditions. Photo-degradation of methyl is following the pseudo first order kinetics.
