Carbon Nanotubes

Single-walled carbon nanotubes (SWNTs) with highly graphitized structure are synthesized by thermal chemical vapour deposition using an improved nitrogen-pretreated Fe-Mo/MgO catalyst. We study the effects of nitrogen pretreatment of Fe-Mo/MgO on the structure and properties of SWNTs. The nitrogen pretreatment of the catalyst promotes the growth of SWNTs. It also enhances the structural features and thermal properties of SWNTs.
