TiO2\Fe3O4 and TiO2\Fe2O3 nanocomposites with various ratios were synthesized by an ultrasonic–assisted deposition–precipitation method and their UV–light decolorization of methyl orange (MO) dye was investigated. The effect of Fe3O4\TiO2 and Fe2O3–TiO2 nanocomposites ratio on the photocatalytic activity and magnetic property of the nanocomposites was studied by comparing their decolorization curves and magnetism in the presence of magnet, respectively. The results revealed that the decolorization efficiency of 1 wt% Fe3O4\TiO2 nanocomposite reached about 40% within 60 min UV irradiation at room temperature. However, this sample showed the least magnetism. Also, the ability of synthesized nanocomposites in holding the adsorbed methyl orange dye on their surface and the effect of pH were investigated<\div>
