Title:
LARGE-DIAMETER, LOW-DENSITY CARBON NANOTUBE, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/171386
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a large-diameter, low-density carbon nanotube, and provides a method capable of preparing a large-diameter, low-density carbon nanotube, which has excellent dispersibility, by using a spherical α-alumina-containing catalyst capable of controlling the growth of a carbon nanotube without deterioration in the quality of the carbon nanotube.
