Synthesis of diverse structured vanadium pentoxides particles by the simplified hydrothermal method

•The three structures of V2O5 particles have been synthesized effectively.•The synthesized specimens have pure composition of V2O5 with shcherbinaite phase.•Employment of stirred autoclave system is crucial to simplify synthetic condition.

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, V2O5 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 HNO3 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.
