Abstract

V₂O₅ nano-arrays with different structural units (i.e. rods, plates, and belts) were prepared by tailoring the protonation and dehydration of vanadate using different acids (HCl, H₃PO₄, HAc, and H₂C₂O₄). The nanobelt-arrays showed a specific capacity as high as 255 mA h g⁻¹, while the nanoplate-arrays showed the best rate capability.
