Fe-TiO₂ Nanoparticles by Hydrothermal Treatment with Photocatalytic Activity Enhancement

Abstract:

Fe-TiO₂ nanoparticles with 5-9 nm sizes were prepared by sol gel method subsequently subjected to hydrothermal treatment at 150°C for 6 h. Titanium (IV) isopropoxide and iron (III) nitrate nonahydrate were used as precursor. The morphology, structure and composition of the Fe-TiO₂ were investigated by X-ray diffraction (XRD), Transmission emission microscopy (TEM) and UV-vis spectroscopy (UV-vis). XRD analysis revealed the prepared samples was dominated with anatase phase and a trace of brookite phase. The TiO₂ crystallite size was reduced as Fe content was increased. Compared with the pure TiO₂ nanoparticles, the Fe-TiO₂ nanoparticles exhibited higher photocatalytic activity in decolorizing methyl orange into non-toxic inorganic products under UV irradiation.
