Fullerenol-d C60(OH)22−24 was synthesized by the method of direct heterogeneous oxidation of fullerene C60, dissolved in o-xylene, by NaOH, dissolved in water, in the presence of interphase catalyst OH. Identification of fullerenol-d was provided by: C–H–N elemental analysis, High performance liquid phase chromatography, IR – and Electronic spectroscopy, Mass-spectrometry. The antioxidant properties of aqueous fullerenol-d solutions were investigated against free radicals, generated by hydrogen peroxide and molecular I2. Measurement of fullerenol antioxidant activity was based on the potentiometric titration of fullerenol solutions by hydrogen peroxide and molecular I2 solutions and vice versa with compact Pt as working electrode. As a comparison, the very popular and strong anti-oxidant – ascorbic acid was used. Pourbaix Diagrams (pH −Eh) for hydrogen-oxygen and iodine forms were constructed. Fullerenol-d is a weaker antioxidant than ascorbic acid, but in contrast, fullerenols-d molecules are able to undergo multiply reversible absorption-desorption of some free radicals.
