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

摘要

The electrochemical formation of self-organized porous structures has recently attracted much attention due to the broad range of nanoscale applications that become accessible through nanopore arrays made of materials such as Al2O3,[1]-[12] Si,[13], [14] and InP.[15], [16] Particularly, the anodic oxidation of Al has been studied in detail and a variety of highly ordered porous oxide structures with a high-aspect-ratio pore geometry have been successfully prepared.[1]-[7] In addition to direct applications, the nanostructures have also been employed as a template for the deposition and fabrication of secondary nanostructures.[9]-[12] Applications include magnetic recording media, optical devices, functional electrodes, and waveguides.
