Microwave synthesis of metal doped TiO2 for photocatalytic applications

Nanostructured metal (Sn, Cu and Ni) doped TiO 2 was successfully synthesized by microwave irradiation method. Metal doped TiO 2 was characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR) and UV–Vis spectroscopy (UV–Vis). The XRD pattern confirms the formation of monoclinic phase TiO 2 and metal doped TiO 2 samples. SEM images show the attractive morphologies for metal doped TiO 2 nanopowders. The photocatalytic activity of the synthesized sample was also studied by the decomposition of methylene blue dye under UV light irradiation.
