The conditions for preparation of porous anodic aluminum oxide templateAAO was studied in this paper. Anodic voltage and electrolyte temperature had great influence on the surface morphology and pores diameter of AAO.The electrolyte temperature should be under 25°C. The holes in the synthesized AAO obtained by the two-step anodization and then reamered were more ordered than those by the one-step anodization. Moreover, Iron oxide nanowire was obtained by using the sol-gel method with AAO as template. The main composition of iron oxide nanowire was amorphous γ-Fe2O3 and the its size was limited by the AAO template.
