Abstract
The present invention relates to entangled-type carbon nanotubes which have a bulk density of 31 kg/m3 to 85 kg/m3 and a ratio of tapped bulk density to bulk density of 1.37 to 2.05, and a method for preparing the entangled-type carbon nanotubes.
Claims4
A method for preparing entangled-type carbon nanotubes, comprising:
- mixing an organic acid and a vanadium precursor in a molar ratio of 1:0.0463 to 1:0.0875 to prepare a mixture;
- mixing the mixture and a cobalt precursor to prepare a catalyst precursor;
- performing first heat treatment on aluminum hydroxide to prepare a support;
- supporting the catalyst precursor on the support and performing second heat treatment on the resulting support to prepare a supported catalyst;
- and
- reacting the supported catalyst with a carbon-based compound.
