| Research Abstract |
Carbon tubes of nanometer level have now been characterized as a new carbon material. Specifically, metal-filled carbon nanotubes could have a variety of industrial applications. Thus the preparation and application of such filled nanotubes are now becoming a very challenging research. Carbon nanotubes have been prepared thus far mainly using an arc-discharge evaporation technique and there have been several attempts to insertmetal into the tubes prepared by the arc-discharge evaporation technique. In this research, We have prepared carbon nanotubes by template carbonization technique using an anodic aluminum oxide film, which has an array of parallel and straight channels with a diameter of nanometer level. The most striking feature of our carbonization method is to allow one to produce monodisperse carbon nanotubes with uniform length, diameter and thickness. Furthermore, by applying the template technique, we have succeeded in preparing Pt metal-filled uniform carbon nanotubes in which the metal is present as either nanorods or nanoparticles. It should be noted that no Pt metal was observed on the outside wall of the tubes.
