Abstract

Carbon fibers were discharged in N₂ and Ar gas at pressures between 200 and 750 Torr by pulsed wire discharge to prepare fullerene. In experiments using N₂ gas, carbon fibers were almost completely evaporated to form soot, while the fibers were not effectively heated in Ar gas due to the occurrence of surface creepage. In the soot prepared in N ₂ gas, we observed C₆₀ and C₇₀ molecules by mass spectroscopy and ultraviolet/visible absorption spectroscopy. Since this method is very simple and inexpensive, mass production of fullerene with high energy-conversion efficiency will be possible by pulsed wire discharge.
