ABSTRACT:
Carbon nanotubes are produced by submerging carbonaceous anode and cathode electrodes in liquid nitrogen or other suitable liquefied materials such as helium or hydrogen, and passing a direct current between the electrodes to strike a plasma arc between the anode and cathode that erodes carbon from the anode and deposits carbon nanotubes on the surface of the cathode.
