Abstract
A capillary-enforced template-based method has been applied to fabricate V2O5-TiO2 composite nanorod arrays via filling mixture of VOSO4 and TiOSO4 solutions into the pores of polycarbonate membrane. For comparison purposes, pure V2O5 nanorod arrays were prepared through the similar template-based method with V2O5 sol and the sol was synthesized through the V2O5-H2O2 route. The nanorods covered completely a large area and projected from the surface of ITO substrate. The addition of TiO2 to V2O5 has demonstrated to greatly affect the Li+ intercalation capacity of V2O5. For example, V2O5-TiO2 nanorod array with molar ratio V/Ti=75/25 delivered 1.5 times discharge capacity of V2O5 nanorods at a current density of 92 mA/g. Such improvement in the intercalation properties was ascribed to the change of crystallinity and possible modification in lattice structure and interaction forces between adjacent layers in V2O5.
