利用纯度为 99 5 %的Al片进行阳极氧化 ,制成多孔氧化铝 ,通过两步纳米复合 ,制备了金属Co纳米孔洞模板 .分别用透射电子显微镜 (TEM)、X射线衍射仪 (XRD)和振动样品磁强计 (VSM)对样品进行了测试分析 TEM观察的结果显示 ,模板孔洞分布均匀、局域有序 ,平均孔径为 30nm左右 ,孔心距约为 5 9nm ;XRD测试的结果表明 ,模板是Co的多晶 ,并且具有明显的 (0 0 2 )取向 ;VSM测得模板的矫顽力为 6 16 4× 10 4 A m ,比Co的块材有很大提高 The porous metal oxide was prepared by anodic oxidation of 99.5% pure Al flake, and a metal Co nanopore template was prepared by two-step nanocomposite method. Transmission electron microscopy (TEM), X-ray diffraction (XRD) The results of TEM observation showed that the distribution of template holes was uniform and localized, the average pore diameter was about 30 nm, and the center distance of the holes was about 5 9 nm. The results of XRD showed that, The template is Co polycrystalline and has a distinct (0 0 2) orientation. The coercivity of the template measured by VSM is 6 16 4 × 10 4 A m, which is much higher than that of Co
