| United States Patent no. 8,043,596, issued on Oct. 25, was assigned to Showa Denko K.K. (Tokyo). | |
| "Method for Producing Vapor Grown Carbon Nanotube" was invented by Tetsuo Soga (Aichi, Japan), Maheshwar Sharon (Maharashtra, India) and Rakesh Ashok Afre (Aichi, Japan). | |
| 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. |
