Abstract:

 By the arc-discharge of carbon composite rods and graphite rods doped with other substances, fullerene mixture of containing about 10% of higher fullerenes was obtained. This provides the base for the separation, purification and further study of higher fullerenes. Moreover, it was found that the existence of perfect graphite structure in the anode rod is the necessary condition for the fullerene formation. Also, It was considered that other substance doped in the anode plays a role as the hot supports in the fullerenes' growing process, which is the reason of the high yield of higher fullerenes.
