【Abstract】 Fullerenes have been prepared from graphite by electric arcing in He gases.The parameters of the arcing process that forms fullerenes,such as the effect of current and pressure of gases on yield of fullerenes were investigated.The formation mechanism of fullerenes derived was discussed.An appropriate temperature field is crucial to improve the yield of fullerene in the arcing process.The optimal condition of preparing fullerenes in the arcing process is: P = 0.04～0.06 MPa,I= 100～150 A.更多还原
