An electrokinetic route to rapid synthesis of nickel hydroxide and nickel oxide nanotubes.
An electrokinetic route was developed for the synthesis of Ni(OH)2 nanotubes in the nanochannel of anodic alumina oxide (AAO) template. The nanotubes in the template were then converted to NiO nanotubes by calcination in air at 300 degrees. Uniform ordered nanotubes were obtained after selecting proper experimental conditions, such as the ionic concentration, the reaction time and the kind of nickel salts. X-ray diffraction (XRD) analysis indicated that the as-prepared Ni(OH)2 nanotubes were crystalline. Thermogravimetric analysis (TGA) was employed to determine the correlation between temperature and weight lose of the nanotubes. The transmission electron microscope (TEM) and scanning electron microscope (SEM) were used to characterize the morphology and structure of the nanotubes.
