Fabrication of carbon nanotubes by anodic aluminum oxide nano-template

Anodic aluminum oxide (AAO) nano template was prepared by a two-step anodization method and Ni particles were carefully deposition at the bottom of pore of the template. Microwave plasma enhanced chemical vapor deposition (MPECVD) method was used grow carbon nanotubes (CNTs) on the template with this nickel as catalyst and CH4 as carbon source.
