摘要
以液体苯（C6H6）为放电介质,二茂铁为催化剂,石墨做电极,可大量制备洋葱状富勒烯（Onion-like Fullerenes：OLFs）。本文重点考察了二茂铁对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：加入二茂铁可提高OLFs的产量;OLFs呈中空椭球状和多面体状,石墨化程度较高,OLFs直径分布可控制在10-30nm范围内。
Onion-like Fullerenes（OLFs） were synthsized by arc discharge in benzene and ferrocene using graphite as electrode.The effect of ferrocene on synthesis of OLFs was discussed.High resolution transmission electron microscopy（HRTEM） and X-ray diffraction（XRD） technique were used to characterize morphology and structure of the products.The results show that the yield of OLFs might be improved if ferrocene is used as catalyst.The degree of graphitization is higher.The diameters of OLFs are in the range from 10 to 30nm.
