摘要: 以多孔氧化铝膜为模板, 在室温下的酸性化学镀镍槽中通过化学沉积法生长出纳米线与纳米管有序阵列. 分别用X射线衍射仪(XRD)与透射电子显微镜(TEM)对纳米线、纳米管阵列进行表征. 并通过对纳米线与纳米管的生长方式进行分析比较, 系统地研究了多孔氧化铝模板的前处理对纳米阵列生长的影响. 结果表明, 生成的纳米线与纳米管均为非晶态的镍磷合金. 室温下镍纳米管的生成主要取决于敏化、活化过程, 而当纳米管的厚度达到一定程度后就不再随时间变化.

Abstract: Ni-P nanowire arrays and nanotube arrays were fabricated by electroless deposition using porous aluminum oxide membrane as templates in acidic coating bath at room temperature. The images of Ni-P nanowires and nanotubes are obtained by transmission electron microscope (TEM), respectively. X-ray diffraction (XRD) and selected area electron diffraction (SAED) are employed to study the morphology and chemical composition of the nanowires and nanotubes. The influence of pretreatment of alumina template on the growth of nano-arrays is studied by comparing the growing ways between nanowires and nanotubes. The results indicate that both Ni-P nanowires and nanotubes are amorphous nickel phosphor alloy. The growth of nanowires and nanotubes mainly depends on sensitization and activation process at room temperature. Using sensitization and activation together as pretreatment will cause the formation of nanowires. Using activation only as pretreatment will cause the formation of nanotubes. The thickness of nanotubes wouldn′t rise with time when it reached a certain degree.
