A method for producing a carbon nanotube, characterized in that oil is sprayed onto a catalyst metal supported on at least one carrier selected from the group consisting of silica gel, alumina, magnesia, silica alumina, and zeolite in a controlled atmosphere at a constant temperature. And an apparatus. According to the present invention, carbon nanotubes can be synthesized in a large amount using inexpensive raw materials using a simple device. |
