摘要

Multi-walled carbon nanotubes (MWNTs) and singlewall carbon nanotubes (SWNTs) are produced by dc arc discharge evaporation. In the case of MWNTs, hydrogen arc discharge was effective to make highly crystallized ones and with the thinnest inner tubes. In Raman spectra of MWNTs, radial breathing modes corresponding to the thinnest inner tube were observed. Mass production of SWNTs by arc discharge evaporation was carried out by arc plasma jet method. Hydrogen gas or addition of 1 percent H_2S gas also was effective to prepare SWNTs by arc discharge.
