Comaprison of Iron Nanowires Fabricated via Porous Anodic Aluminium Oxide Template by a.c and d.c. Electrodeposition

Abstract

In present study nanowires of iron were fabricated by both alternate current (a.c) and direct current (d.c) by using nanoporous anodized aluminium as a template. Nanowires in anodic alumina template were fabricated by electrodeposition method. It has been investigated that synthesis of nanowires is possible by using both a.c and d.c electrodeposition. The nanowires obtained by using a.c electrodeposition were elongated and more stable where as nanowires fabricated by using d.c electrodeposition were less stable. Optimum time attained for the synthesis of nanowires in a.c depostion was 5 minutes where as in case of d.c deposition nanocrystals of different shapes were obtained due to less stability. Average diameter of nanopores obtained in anodized aluminium was 150 nm by using phosphoric acid as a electrolyte. Length of nanowires obtained by using a.c and d.c electrodeposition was 683 nm and 640 nm respectively.
