Abstract:
1. A method for producing nano-scale carbon products, comprising the steps of: contacting a fused-salt electrolyte with first and second graphite electrodes; simultaneously; and alternately performing steps (A) and (B) in multiple repetitions as follows, so that each electrode is alternately applied as a cathode and an anode; (A) applying to the electrodes for at least 30 seconds a first voltage such that the first electrode is at a cathodic potential relative to the second electrode, the first voltage generating a predetermined cathode current density at the first electrode of between 1.5 A·cm (B) applying to the electrodes for at least 30 seconds a second voltage such that the second electrode is at a cathodic potential relative to the first electrode, the second voltage generating a predetermined cathode current density at the second electrode of between 1.5 A·cm
