Overview
There are several methods employed to make carbon nanotubes. These methods include chemical vapor deposition (CVD), arc discharge and laser ablation. In general, the CVD method has shown the most promise in being able to produce larger quantities of nanotube (compared to the other methods) at lower cost.The CVD method is usually done by reacting a carbon-containing gas (such as acetylene, ethylene, ethanol, etc.) with a metal catalyst particle (usually cobalt, nickel, or iron) at temperatures above 600°C. However, even this method fails to produce large quantities of nanotubes of uniform diameters.
Researchers at the University of Maryland have developed methods for producing, pure high density nanotubes of relatively uniform diameters (<~10 nm) in a new simple one-step process.
