THE METHOD AND DEVICE FOR PRODUCING HIGHER FULLERENES AND NANOTUBES

摘要

A method for producing a mixture of higher fullerenes and nanotubes is provided through annealing carbon clusters during a pulsed auto-regulated action of a n electric current arc discharge between graphite electrodes. The electrodes a re located in a hydrocarbon liquid able to differentially dissolve higher fullerenes of C70 or higher compared to lower fullerenes up to and including C60. The puls ed auto-regulated electric current arc discharge is continued until the higher fullerenes or the lower fullerenes are dissolved.
