Abstract

In this letter, we utilize a simplified hydrothermal method without any addition of catalyst to synthesize one-and three-dimensional structured pure vanadium pentoxide (V2O5) particles, V2O 5 nano-belt, micro-flower and micro-plane-flower. The synthesis is made possible by the formation of shcherbinaite phase and its cleavaging property along (001) facet by physical force. The V2O5 nano-belt has been derived from the V2O5 precursor in de-ionized (D.I.) water without catalysts by using stirred autoclave system. And V2O5 micro-flower and micro-plane-flower have been synthesized in ethylene glycol solvent under controlled pH condition by HNO 3 or NH4OH. The synthesized nano-belts are less than 100 nm in width and less than 50 nm in thickness, respectively. The diameters of the synthesized micro-flower and micro-plane-flower are 5-8 μm. It is demonstrated that the prepared specimens are pure V2O5 composition with shcherbinaite phase.
