摘要: 铝在硫酸溶液中经直流阳极氧化,得到多孔铝阳极氧化膜(AAO). 以AAO膜为模板,通过交流电沉积的方法,在AAO模板孔内成功组装了Fe纳米线.TEM分析表明,Fe纳米线的长度约为2.5 μm,其长度分布十分均匀;粗细均匀,直径约为25 nm. XRD实验分析证实,所制备的Fe纳米线为α-Fe.选区电子衍射(SAED)实验分析表明,α-Fe纳米线具有单晶结构.

Abstract: Fe nanowire arrays have been prepared by electrodeposition in porous anodic aluminum oxide template from a composite electrolyte solution. These nanowires have uniform diameter of approximate 25 nm. The micrographs and crystal structures of Fe nanowires are studied by transmission electron microscopy (TEM),selected-area electron diffraction (SAED),and X-ray diffraction(XRD).It is found that each nanowire is essentially a single crystal and has a different orientation in the array.
