Abstract: The highly ordered anodic aluminum oxide (AAO) template was prepared with two-step anodization. The AAOtemplate was carried out wet etching process using a mixture of phosphoric acid and chromic acid, NaOH, and H3PO4solutions. The relationship between mass loss of AAO template and etching time was studied. The results indicate that 3wt % H3PO4 solution is a more mild and effective etchant comparing with these etchants, and the mass loss is linearwith etching time. SEM investigations show that alumina nanowires were obtained with high yield by etching AAOtemplate. And, the growth of alumina nanowires was closely related to the etching time.
