| abstract |
The invention provides a method for producing carbon nanotubes, comprising spraying an oil onto a catalyst metal supported by at least one support selected from the group consisting of silica gel, alumina, magnesia, silica-alumina and zeolite which is placed in an atmosphere that has been controlled to a specific temperature, and an apparatus therefor. According to the invention, a large amount of carbon nanotubes can be synthesized from inexpensive raw materials by using a simple apparatus. |
