Title:
METHOD FOR SEPARATING AND REFINING CARBON NANOTUBE
Document Type and Number:
Japanese Patent JP2590442
Kind Code:
B2
Abstract:
PURPOSE: To relatively easily and surely remove carbon impurities from a carbon nanotube contg. graphite and amorphous carbon as the carbon impurities and to obtain a high quality carbon nanotube.
CONSTITUTION: A metal chloride of graphite as an interlaminar compd. is prepd. from a carbon nanotube contg. graphite and amorphous carbon, the interlaminar metal chloride is reduced to superfine metal particles in a vapor phase or in a liq. and then oxidation treatment is carried out under heating to separate and remove the graphite and amorphous carbon.
