Two Fe-doped (ca. 1 at.%) homogeneous graphite electrodes (different graphite microcrystals, degree of graphitization and, thereby, electrical conductivities) electrodes were used in the process of production of single-walled carbon nanotubes in Ar-H2 arc plasma under pressure 26 kPa. The C2 content (namely carbon vapor pressure) and temperature distributions in the arc plasma were determined using optical emission spectroscopy. The mechanism of CNT formation based on carbon dimers as the building blocks seems to be at least questionable.
