摘　　要：利用氯化铁为催化剂前驱体 ,结合悬浮催化剂法和基体法的优点 ,采用一种我们称之为悬浮催化 -基体的新方法在 70 0℃生长出了管壁清洁、直径均匀的纳米碳管 ,同时讨论了经不同时间氢气预处理的催化剂铁颗粒对生长纳米碳管直径和缺陷的影响 .实验显示该方法很有希望实现纳米碳管廉价。In this paper,high quality and clean carbon nanotubes were synthesized by the floating based new method taking FeCl 3 as the catalyst precursor. This new method combined the merits of the floating catalyst method and the based method.The influence on diameter and defects of carbon nanotubes owing to the different H 2 pre reduction time of deposited Fe cluster was discussed.The experiment shows that this floating based method with FeCl 3 as the catalyst precursor is a promising method for cheap and mass growth of carbon nanotubes.
