Hydrothermal synthesis of vanadium pentoxide nano structures and their morphology control

Different morphologies of vanadium pentoxide (V2O5) from 1D to 3D, including nanospheres, nanowires, urchin-like and flower-like nanostructures, have been synthetized by a simple hydrothermal method. Some parameters, such as the reaction temperature, the volume of polyvinyl pyrrolidone (PVP) and possible formation mechanisms of different V2O5 nanostructures were discussed. The results demonstrate that PVP and the reaction temperature play a critical role on the morphology of vanadium pentoxide. Crown Copyright (C) 2012 Published by Elsevier Ltd and Techna Group S.r.l.
