Abstract: The influences of electrode surface structure and organic additives such as aniline and o-aminophenol on the electroreduction of fullerene are investigated in this paper.It is found that the activity of electroreduction of fullerene and fulleride anions ls dependent on the electrode surface structure.The reduction current of fullerene at polycrystal electrode is higher than those at Pt (111) and Pt (110).Some negative shifts of reduction potential of C₆₀^- and C₆₀^2- at Pt (111) and Pt (110) are observed.In addition, the effects of some organic additives, such as aniline and o-aminophenol on the reduction of fullerene are also investigat-ed.Different reduction mechanisms are proposed for these two systems, i.e.one is due to the formation of C₆₀^-aniline complex, the other is due to chemical reaction between C₆₀ with o-aminophenol in the reduction process.
