摘要：

In the present work, we report formation of high aspect ratio zirconia nanotubes by electrochemical anodization of zirconium in a 1 M (N-H-4)(2)SO4 electrolyte containing 0.5 wt% NH4F. Highly self-organized zirconia nanotubes can be formed with a diameter of approximate to 50 nm and a length of approximate to 17 mu m, i.e. with an aspect ratio of more than 300. The nanotubes show a distinct smooth and straight morphology. XRD investigation reveals that the nanotubes have a cubic crystalline structure directly after anodization, that is, without any further annealing. (c) 2005 Elsevier B.V. All rights reserved.
