單壁納米碳管的純化研究
A purification method to remove the metal catalysts and impurity carbon materials from arc-discharge-grownsingle-walled carbon nanotubes (SWCNTs) has been developed. Microporous membrane and the oxidation in the airfor the crude SWCNTs were used to eliminate the coexisting metal catalysts nanoparticles, carbon nanoparticles andamorphous carbon. Then we used the high resolution transmission electron microscopy (HRTEM) to characterizethe crude SWCNTs prepared by arc-discharge method and the purified SWCNTs. The Raman spectra and thethermogravimetric analysis (TGA) were also utilized to analyze the approach of our purification for SWCNTs. Withthis method the SWCNTs with the purity more than 95% could be obtained.
