Self‐Organized High‐Aspect‐Ratio Nanoporous Zirconium Oxides Prepared by Electrochemical Anodization

Abstract

Getting organized: Highly ordered porous ZrO2 layers and nanotubes with very high aspect ratios (see SEM image) can be prepared by direct anodization of Zr in fluoride-containing electrolyte. The morphology of the layers is strongly affected by the electrochemical parameters used. Under optimized conditions, the ZrO2 layers have a cubic structure and are candidates for use in applications such as catalysis, due to their high surface area and defined geometry.
