Abstract
Soot containing fullerenes is produced by impressing a DC voltage between a carbonaceous anode and a cathode in an airtight chamber maintained in an inert gas atmosphere to cause arc discharge to occur. After termination of the impression of the DC voltage, an inert gas is blown into the chamber to fluidize the soot. The fluidized soot is discharged from the chamber and is brought into contact with a solvent to recover the fullerenes.
