液苯介质放电制备洋葱状富勒烯

摘要: 以液体苯（C6H6）为放电介质，石墨做电极，成功地制备了洋葱状富勒烯（Onion-like Fullerenes,OLFs）。重点考察了电流对OLFs产量的影响，利用高分辨透射电镜（HRTEM）和X-射线衍射（XRD）对所得产物进行了表征。结果表明：电流大小是影响OLFs产量的主要因素，所制OLFs直径分布可控制在10nm～30nm范围内。

Abstract: Onion-like Fullerenes (OLFs) were synthesized by arc discharge in benzene using graphite electrodes. The effect of experimental parameters on the morphologies and structures of the OLFs was investigated by HRTEM and XRD. Results show that electric current is the main factor and the diameters of the OLFs can be controlled in the range between 10 and 30nm.
