Electric-arc synthesis of soot with high content of higher fullerenes in parallel arc

Аннотация

Soot with a relatively high content of higher fullerenes (C₇₆, C₇₈, C₈₀, C₈₂, C₈₄, C₈₆, etc.) is synthesized in a parallel arc upon evaporation of pure carbon electrodes. The content of higher fullerenes in soot extract amounts to 13.8 wt % when two electrodes are simultaneously burnt in electric-arc reactor. Such a content is comparable with the content obtained upon evaporation of composite graphite electrodes with potassium carbonate impurity.
