Nanorods of several oxides, with diameters in the range of 10-200 nm and le
ngths upto a few microns, have been prepared by templating against carbon n
anotubes. The oxides include V2O5, WO3, MoO3 and Sb2O5 as well as metallic
MoO2, RuO2 and IrO2. The nanorods tend to be single-crystalline structures.
Nanotube structures have also been obtained in MoO3 and RuO2.
