Catalyst composition for preparing carbon nanotube |
摘要 |
The present invention relates to a catalyst composition for preparing carbon nanotube and a process for preparing carbon nanotube using the same. More particularly, this invention relates to a process for preparing carbon nanotube by the chemical vapor deposition method through the decomposition of lower saturated or unsaturated hydrocarbons using a multi-component metal catalyst composition containing active metal catalyst from Co, V, Al and inactive porous support. Further, the present invention affords the carbon nanotube having 5˜30 nm of diameter and 100˜10,000 of aspect ratio in a high catalytic yield.
