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.

纳米碳管是一种新型的碳材料。具体而言，金属填充的碳纳米管可以具有各种工业应用。因此，这种填充纳米管的制备和应用现在成为一个非常具有挑战性的研究。迄今为止，碳纳米管的制备主要使用电弧放电蒸发技术，并且已经有几次尝试将金属插入到通过电弧放电蒸发技术制备的管中。在本研究中，我们利用模板碳化技术，在阳极氧化铝膜上制备了直径为纳米级的平行和直通道阵列的碳纳米管。我们的碳化方法最显著的特点是允许生产具有均匀长度、直径和厚度的单分散碳纳米管。此外，通过应用模板技术，我们已经成功地制备了Pt金属填充的均匀的碳纳米管，其中金属是作为纳米棒或纳米颗粒存在。应该注意的是，在管的外壁上没有观察到Pt金属。
