摘要

V2O5 center dot xH(2)O bundle-like nanostructures composed of nanobelts have been synthesized by a simple hydrothermal method with the aid of Co2+. The widths, thickness and lengths Of V2O5 center dot xH(2)O nanobelts are 80-100 nm, 10-20 nm, and several micrometers, respectively. The morphologies and the crystallographic structures of the V2O5 center dot xH(2)O bundle-like nanostructures were characterized by X-ray powder diffraction (XRD), fieldemission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and electron diffraction (ED). The effects of the inorganic ions and reaction temperature on the morphologies of the resulting products have been investigated.
