“…Design improvements: graphite electrode replacement and electrode slag removing without breaking vacuum is possible. Huczko et al (1996) [56] dc and ac arc discharge Fullerene yields were quite similar for both ac and dc modes. However, for the dc mode, the optimal current is much lower, thus making the process more efficient regarding energy consumption.…”

Carbon nanostructures have received much attention for a wide range of applications. This paper reviews the historical role of plasmas in the gas-phase synthesis of carbon nanostructures and the present plasma technologies for industrial production purposes. It enumerates the advantages and disadvantages with respect to concurrent technologies commonly employed nowadays. Finally, some carbon nanostructures produced in our laboratory will serve as examples of the plasma processes potential.

“…A method of fullerene soot (FS) production process described by W. Krätschmer et al in a plasma of the direct current (DC) arc in a helium atmosphere at pressure of 13.3 kPa [1] and its various modifications remains one of the most effective until recently [2][3][4][5][6]. At the beginning of the 90s of the last century, there appeared many scientific publications on new methods for producing fullerenes and on the influence of various parameters on their formation [7][8][9][10][11].…”

The results of the effect of helium pressure in the chamber on the amount and composition of the produced fullerenes (C 60 , C 70 , etc.) synthesized in the arc plasma with graphite electrodes are presented. The findings obtained when the arc is powered by a direct (DC) and alternating (AC) currents of low frequency were compared in the same chamber with the electrodes located at the same angle to each other. These two methods are drastically different. The complete conversion of graphite into fullerene soot in AC occurs, but a part of the graphite is converted into a cathode deposit that does not contain fullerenes in DC, the relative amount of which increases when decreasing the helium pressure in the chamber. The highest fullerene content in fullerene soot of 10.2 wt.% is produced at a pressure of 127.5 kPa in AC arc, but in DC arc, the highest content of fullerenes in fullerene soot of 8.3 wt.% is produced at a pressure of 33.3 kPa.
