Abstract

In the present work, vanadium pentoxide (V2O5) nanoparticles have been successfully prepared by a simple hydrothermal method. The effect of annealing on its photocatalytic property for methylene blue (MB) dye was successfully studied. V2O5 phase is confirmed by XRD, Raman spectra, while FTIR is used for functional group detection. Agglomerated nano particle morphology was observed in SEM. The observed direct band gap of V2O5 is 2.63-2.81 eV calculated using UV Visible spectroscopy. Finally, the photocatalytic property of V2O5 was studied for MB dye. The results obtained indicate a promising and enhanced degradation property of prepared calcinated product V2O5. Very small quantity calcinated product shows about 68% degradation of MB within 80 min. Also rate constant for calcinated product is 9.9×10-5 S-1 .
