Fe nanowire arrays were prepared by electro-deposition using 3D Mn-doping SBA-16 film. Fe-deposited SBA-16 film was treated with a 2% HF aqueous solution to remove the SiO₂ template. The specimen was calcined in air at 550℃ for 4 h. Both SEM and TEM results indicate that the nanowires are paralleled with each other and have uniformed diameter. XRD, electron diffraction and HRTEM investigations demonstrate that the crystalline structures of these nanowires are porous crystal of iron oxide.

Key words: SBA-16 film, electrodeposition of Fe, porous Fe₂O₃ nanowire
