Abstract
Fullerenes were synthesized by pulse arc discharge of 50 Hz-10 kHz, 150 A-500 A with graphite electrode and He ambient (about 80 Torr). Fullerene productivity was evaluated with colorimetry by toluene dissolution and with TOF-MS analysis. As a result, fullerene yield achieved a maximum at 500 Hz, 200 A, and content rate of higher order fullerenes increased with higher frequency. In addition, correlation of each fullerene was evaluated by statistical processing from TOF-MS spectra and the fullerene formation mechanism was examined.
