Abstract

A new path of fullerene formation via pyrolysis of ragged single-wall carbon nanotubes (r-SWNTs) which were treated by ultrasonication with an organic solvent followed by heating in oxygen gas is reported. Mass spectrum and high-performance liquid chromatography results indicated that C 60, C 70, and higher fullerenes existed in products obtained through the pyrolysis of the r-SWNTs at above 800 °C in vacuum. We suggest that the pyrolysis of r-SWNTs originates from holes and defects in the r-SWNTs.
