Title:
PRODUCTION METHOD AND DEVICE FOR SINGLE LAYER CARBON NANOTUBE
Document Type and Number:
WIPO Patent Application WO/2004/099072
Kind Code:
A1
Abstract:
AC arc discharge A is generated between graphite electrodes (20R, 20L) oppositely provided in a direction perpendicular to the pipe axis in a reaction container (10) kept in an H2-Ar mixture gas atmosphere to produce net-like deposit of a single-layer carbon nanotube in a space formed by connecting the graphite electrodes (20R, 20L) with the inner wall of the reaction container (10). Next, when an atmosphere in the reaction container (10) is switched to an O2-Ar mixture gas and the interior of the reaction container (10) is heated by a heating mechanism (14), carbon impurities such as carbon nano-particles and amorphous carbon contained in the net-like deposit are gasified and removed from the net-like deposit. Accordingly, a single-layer carbon nanotube can be produced and refined using the same reaction container (10) to produce a high-purity, single-layer nanotube easily.
