Effects of Preparation Methods on Morphologies of Alumina Templates and Cu Nanowires

Abstract:

Metallic nanowires have been widely studied in various fields due to its special properties such as electronic, optical and chemical. Conventional methods for the preparation of Cu nanowires are usually not accessible by using porous alumina templates due to restriction on using two-step anode oxidation, sputtering Au film, etc. In this paper, the porous alumina template was prepared by one-step anodization. An Al sheet was employed as cathode instead of a valuable Pt or graphite electrode. The Al substrate of alumina template was removed by using the concentrated hydrochloric acid/ethanol solution instead of a heavy metallic salt solution of SnCl₄, HgCl₂ or CuCl₂ used in documents. Cu nanowires were prepared in the porous alumina template by electro-deposition with moving cathode. Some of Cu nanowires were neatly assembled together to form a hemispherical structure and were protected from oxidation. The operations can reduce the cost and simplify the operation.
