Claim 0:
1. A method of making ζ-V2O5 nanowires comprising:
hydrothermally reacting soluble vanadium source, wherein the vanadium is 4+, 5+, or a combination thereof, and a copper source, wherein copper is 1+ or 2+, in the presence of a reducing agent to provide β-CuxV2O5 (0.33<x<0.66) nanowires; and
reacting the β-CuxV2O5 nanowires in solution containing an oxidizing agent, thereby topochemically leaching Cu ions from the β-CuxV2O5 nanowires to provide ζ-V2O5 nanowires, said ζ-V2O5 nanowires showing no copper signal when analyzed by energy dispersive X-ray spectroscopy.
