In this paper, structural and morphological properties of vanadium oxides (V2O5) nanoparticles have been studied. V2O5 nanoparticles were synthesized using a simple chemical method by sodium metavanadate as precursor and Cetyl trimethylammonium bromide (CTAB) as surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM) and X-ray diffraction (XRD). As there are many forms of vanadium oxides produced during this process, x-ray diffraction (XRD) technique was used to identify V2O5 phase. particles was around 5 nm as estimated by HRTEM technique and average diameter of annealed nanorods was around 9 nm as estimated by XRD technique and direct FESEM observation. The surface morphological studies from SEM depicted that nanorods were appeared after annealing process. The effect of CTAB surfactant on the particle morphology was also studied and the results show that the CTAB can reduce the particle size of nanorods to less than 10 nm.
