A new homemade are fullerene generator used in this experiment is reported. The comparation of yields of fullerenes (C60/C70 mixture) was studied by different power supplies (AC and DC), different gaps of two graphite rods and different He pressure between 0.4×104- 2.8×104 Pa. In our experiment, the highest yield up to 13% was achieved, when DC discharge was used and the optimum He pressure was near 0.8×104 - 1.6×104 Pa. The mixed fullerene was analyzed by electron impact masa spectnun (EIMS). The relative amount af C60 to C70 was 4.2 to 1. After column chromatography aeperation with hexane on alumina, 99.9% Cso was obtained. FTIR and 1aC-NMR epectrum were ueed to characterize the pure C60 samples. |
