Title:
METHOD FOR PRODUCING SINGLE-WALLED CARBON NANOTUBE-CONTAINING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2018/123796
Kind Code:
A1
Abstract:
The present invention provides a method for producing a carbon nanotube-containing composition, wherein a catalyst carbon source solution containing a carbon compound, an iron compound and a sulfur compound is introduced into a reaction tube in a mixed carrier gas of hydrogen and an inert gas. According to the present invention, the molar concentration of carbon atoms in the carbon compound is from 0.16 mmol/L to 0.53 mmol/L (inclusive) based on the mixed carrier gas in a standard state; the ratio of the number of sulfur atoms in the sulfur compound to the number of iron atoms in the iron compound is 0.7-2.4; the hydrogen concentration in the mixed carrier gas is from 50% by volume to 90% by volume (inclusive) in a standard state; and the carbon compound contains an aromatic compound. According to the present invention, single-walled carbon nanotubes having high crystallinity are able to be obtained highly efficiently.
