| 摘要 |
An electric arc furnace and method for forming tubular carbon nanostructures comprising a first electrode (cathode) and an a second electrode (anode) opposite the first electrode, sources of voltage (V) and current (A) to create charged particles (Ie) and produce an arch between the electrodes, a source of a gas to surround the arc, and a source of carbon precursor positioned adjacent the anode and within the arc, wherein the arc is maintained at a pressure and high temperature for a time sufficient to heat the carbon precursor to form carbon nonotubes upon the anode.
