Fabrication of porous alumina templates for electrochemical synthesis of nanowires
- Conference date: 21–23 December 2010
- Location: Penang, Malaysia
Porous alumina membranes are often used as templates for synthesizing nanowire arrays due to their welldefined pore structures and uniform pore sizes. In this study, one-dimensional metallic nanowire arrays with wellcontrolled dimensions and structures were synthesized via template-directed electrodeposition using in-house fabricated alumina membranes as scaffolds. Porous alumina membranes with uniform nanoscale pore diameters and interpore distances were fabricated by a two-step anodisation technique. Pore diameters, depths as well as spacings between adjacent pores were carefully controlled by the anodizing conditions used. The morphologies and structures of the templates and the nanowires produced were reported using scanning electron microscopy (SEM) and X-ray diffraction for characterization.
