    Abstract:

    Porous vanadium oxide nanotubes (VNTs) are generated by electrospinning technique and following sintering treatment. In this paper, we choose commercial vanadium oxides and benzyl alcohol and Isopropanol as the raw materials to form low-cost inorganic vanadium sol solution followed the appropriate addition of poly(vinylpyrrolidone) (PVP) as electrospinning vanadium precursor[1]. Thus, we can prepare the one-dimensional (1D) VNTs, which mainly containing V2O5-sol and PVP, followed by varying the holding time of sintering. Crystal structure and the morphology of electrospun VNTs are analyzed by using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). X-ray photoelectron spectroscopy (XPS) also displays carbon remained after PVP sintered. The electrospun VNTs are about 400 - 700 nm in diameter, and 2-10 μm long with various degrees of porous interconnected fibrous morphology which could be seen by SEM and TEM images. And the degrees of the fracture of the porous vanadium pentoxide nanotubes are various with different holding time at high temperature.
