In addition, the method of forming at least one carbon nanotube is comprised of conducting a chemical reaction process such as catalytic decomposition, pyrolysis, chemical vapor deposition, or hot filament chemical vapor deposition o grow at least one nanotube on the surface of the nano-supported catalyst (108).Other References
