Abstract

A new method for efficiently generating higher fullerenes is reported. By utilizing the arc-discharge of boron-doped graphite (bulk boronized graphite) electrodes, we have found that the yield of higher fullerenes (C₇₆C₉₆) in toluene extracts becomes 35-40 wt% with an optimum boron doping, which is more than twice as large as that obtained in the conventional arc-discharge of 100% graphite rods. A typical absolute yield of the higher fullerenes in soot is 5-6 wt%. The results suggest that some boron-carbon binary clusters play an important role in an early stage of the formation of higher fullerenes.
