摘要：
The present invention relates to a method for producing large-diameter, low-density carbon nanotubes. The method uses a catalyst containing spherical α-alumina that is capable of controlling the growth of carbon nanotubes without deteriorating the quality of the carbon nanotubes. The use of the catalyst makes the carbon nanotubes highly dispersible.
