Abstract

Nanocrystalline ethylene glycol mediated pure and vanadium doped tin oxide (VTO) powders of about 5-20nm in size have been prepared by simple sol-gel method. The molecular structural properties of the prepared pure SnO2 nanopowders annealed at different temperatures (80-600○ C) have been characterized by Fourier transform infrared spectroscopy (FTIR). PL emission spectra show that the introduction of V2+ into the SnO2 host, the defects still play a dominant role with respect to the luminescence processes. The prepared VTO nanoparticles exhibit photocatalytic activity in the degradation of methyl orange, indicating that the SnO2 nanostructure is promising as a semiconductor photocatalyst..
