摘要: Abstract Highly ordered zircaloy-4 (Zr-4) oxide nanostructures with nanoporous or nanotubular morphologies are prepared using two-step anodization. The first-step anodization in ethylene glycol (EG) electrolyte containing 0.3 wt% ammonium fluoride and 0.2 wt% de-ionized water produced bundled nanotubes on the surface of Zr-4. as-grown obtained by were detached ultrasonically ethanol, leaving an concave Zr-4 substrate. When substrate was secondly anodized, clear open top surfaces fabricated. In addition, could be controlled to have tubular porous structure only changing from EG glycerol second
