An efficient and cost-effective method for treating carbon nanotubes (CNTs) is provided. The method includes comprising: dispersing said carbon nanotubes in a dispersing medium to prepare a dispersion system; mixing said dispersion system with adsorbent so that type-specific carbon nanotubes contained in said dispersion system are absorbed onto the adsorbent, wherein the adsorbent is modified by a chemical/biological modifier so as to have different adsorption selectivity to carbon nanotubes of different types; and separating the adsorbent from the dispersion system, whereby the type-specific carbon nanotubes adsorbed onto the adsorbent is separated from the carbon nanotubes of another type enriched in the dispersion system; carbon nanotubes produced by the treatment method, and CNTs devices comprising thereof.

Method for treating carbon nanotubes, carbon nanotubes and carbon nanotubes device comprising thereof

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.

Carbon nanotubes, a method of preparing the same and an element using the same

A method for treating carbon nanotubes is provided. In the method for treating carbon nanotubes (CNTs), the CNTs are treated with SOgas at an elevated temperature, for example, at a temperature in the range of 385&#xb0; C. to 475&#xb0; C.
