Abstract

In the present work the way to grow SWCNTs, large enough to accommodate
C-82 fullerenes, using nonmagnetic metal catalysts is demonstrated. The
growth was carried out in a water-cooled dc arc-discharge Kratschmer
generator with horizontally aligned electrodes. Different methods such
as Raman and optical spectroscopy, TGA and TEM were used for
characterization of the materials produced under various growth
conditions. The concentration of sulphur promoter strongly influences
the yield of SWNTs and affects their diameter distribution. The highest
relative concentration of SWCNTs with diameters larger than 1.5 nm was
found for an addition of 0.9-1.3 at% of sulphur to PtRh catalysts.
