A plasma-assisted synthesis of TiO2/SnO2 nanocomposite is described. In this approach, a precursor containing a mixture of [TiCl3 and SnCl2] exposed to electric discharge was oxidized by plasma-generated reactive species (HO center dot/H2O = 2.85 eV/SHE). SnO2 microstructures with a diameter of 10-40 mu m were coated by thin layers TiO2 nanorods with mean diameter of 6-8 nm. The obtained TiO2/SnO2 nanocomposite was characterized by transmission and scanning electron microscopy, X-ray diffraction and Fourier transform infrared. TiO2/SnO2 nanocomposite was found to be a promising new material for the photocatalytic discoloration of aqueous Remazol Brilliant Blue-R dye under daylight and UVA light sources, due to the combined effects of large specific surface area and heterojunction which efficiently separates the electron-hole pairs delaying the charge recombination. The leaching test indicated that the nanocomposite is stable easily reusable.
