CARBON NANOTUBES AND PRODUCTION METHOD THEREOF |
| 摘要 |
The present invention relates to a method of producing carbon nanotubes, comprising a catalyst particle forming step of heating and reducing a catalyst raw material to form catalyst particles and a carbon nanotube synthesizing step of flowing a raw material gas onto the heated catalyst particles to synthesize carbon nanotubes, wherein a carbon-containing compound gas without an unsaturated bond is flowed onto the catalyst raw material and/or the catalyst particles in at least one of the catalyst particle forming step and the carbon nanotube synthesizing step. |
