Method for producing carbon nanotubes |
| abstract |
A method for producing carbon nanotubes according to the present invention comprises a growth step of growing CNTs on a base material (12) and a cleaning step of supplying a water-containing cleaning gas into a growth furnace (13) to perform cleaning, wherein the cleaning is performed in the cleaning step in such a manner that the formula: 0.7 <= (2[CO2]+[CO])/[H2] <= 1.3 can be satisfied wherein [H2], [CO2] and [CO] respectively represent the concentrations of hydrogen, carbon dioxide and carbon monoxide in a gas contained in the growth furnace (13). |
