Highly ordered Ni nanotube and nanowire arrays were fabricated via electrodeposition. The Ni microstructures and the process of the formation were investigated using conventional and high-resolution transmission electron microscope. Herein, we demonstrated the systematic fabrication of Ni nanotube and nanowire arrays and proposed an original growth mechanism. With the different deposition time, nanotubes or nanowires can be obtained. Tubular nanostructures can be obtained at short time, while nanowires take longer time to form. This formation mechanism is applicable to design and synthesize other metal nanostructures and even compound nanostuctures via template-based electrodeposition.
通过电沉积制备了高度有序的镍纳米管和纳米线阵列。使用传统和高分辨率透射电子显微镜研究了镍的微观结构及其形成过程。在此，我们展示了镍纳米管和纳米线阵列的系统制备方法，并提出了一种独特的生长机制。通过不同的沉积时间，可以获得纳米管或纳米线。短时间内可获得管状纳米结构，而纳米线的形成则需要更长时间。这种形成机制适用于通过基于模板的电沉积来设计和合成其他金属纳米结构甚至复合纳米结构。
