Surfactant-assisted of vanadium oxide (V2O5) nanopaeticles

In this paper vanadium oxide nanoparticles were synthesized in the presence of cetyl trimethylammonium bromide (CTAB) surfactant. The physico-chemical properties were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and UV-Vis spectrophotometer. As there are many forms of transitionvanadium oxide, XRD technique was used to identify the phases of VO2 and V2O5. The SEM images showed that the samples changed to silk-worm shaped after annealing process. The particle size of sample was around 8 nm in diameter. The absorbance peak showed the small bandgap energy of 2222 ev.
