Abstract
Carbon nanotubes, a method for preparing the same and an element using the same are provided. The method for preparing carbon nanotubes includes synthesizing carbon nanotubes from carbon source using an arc-discharge method in the presence of catalysts and promoter, wherein the promoter contains an element capable of reducing the surface energy of carbon nanotubes. Carbon nanotubes with high purity and narrow diameter distribution can thus be prepared.
