Characterization of the one-dimensional growth of V2O5 nanofibers

Highly crystalline one dimensional V2O5 nanofibers was synthesized by using a simple and direct hydrothermal technique at 220 °C of 7-24 hrs reaction times.Structural study by powder X-ray diffraction pattern shows that synthesized V2O5 has highly crystalline in nature possessing an orthorhombic phase that have grown along the [010] direction of forming nanofibers (Fig 1).Morphology study by FESEM and TEM of V2O5 further confirm the formation of nanofibers where nanofibers are up to several micrometers long and 20-25 nm thick.The SAED pattern recorded perpendicular to growth axis of the V2O5 nanofibers shows spot pattern which could be attributed to the [001] zone-axis diffraction orthorhombic phase proving the crystalline nature of V2O5 nanofibers.Finally, in a HRTEM image the lattice fringes with a spacing of 4.06 matching to the (101) plane of V2O5 evidently proving information that the nanofiber has grown along the [010] direction, this is also in good agreement with the XRD outcomes.
