摘要
Well-ordered Co nanowire arrays formed on the porous anodic aluminum oxide (AAO) templates prepared by a two-step anodization technique have been used in the fabrication of well-aligned carbon nanotubes. Designed Co nanowire arrays can be made by controlling the pore arrays on AAO templates. By using them as a catalyst it is possible to fabricate the designed carbon nanotube arrays. Carbon nanotubes fabricated by disproportionation of CO were well graphitized, uniform in diameter and aligned vertically with respect to the plane of the template. It has been suggested that CO is an ideal precursor in fabrication of carbon nanotubes.
