The oxidation of fullerenes (C60, C70) with various oxidants under ultrasonication
The reaction of C60, under ultrasonication, with various oxidants, such as 3-chloroperoxy benzoic acid (Fluka 99%), 4-methyl morpholine N-oxide (Aldrich 97%), chromium (VI) oxide (Aldrich 99.9%), and the oxone® monopersulfate compound, causes the oxidation of fullerenes at room temperature. The FAB-MS spectra and HPLC profile confirmed that the products of fullerene oxidation were [C60(O)n] (n=1∼3 or n=1). C70 also reacted, under ultrasonication, with various oxidants, but the reaction rate of C70 was lower than that of C60.
