The oxidation of carbon samples: C-60, C-60(OH)(n), C-60(O)(n), C-60(H)(n), C-70, diesel particulate matter (PM), activated carbon. and graphite was carried out using a thermogravimetry equipped with a mass spectrometer. It was found that incorporation of O, OH, and H onto C-60 surfaces promotes oxidation at a temperature lower than that without incorporation. This finding is helpful to understand the mechanism of PM removal in plasma discharges. A simple oxidation mechanism of C-60 and its derivatives is given.
