Abstract:	This article presents the fabrication of alumina nanowires by etching AAO templates using chromic acid solutions. Our work has shown that an aging process in the ambient atmosphere for a relatively long time is indispensable to obtain uniform, small diameter alumina nanowires, which may be due to the release/redistribution of internal stresses of AAO template. The study of the formation mechanism leads to the optimization of the fabrication procedure. Alumina nanowires with a diameter of 5-10 nm have been achieved with a very good uniformity, an excellent surface coverage, and a relatively large BET surface of 50 m2/g.
