摘要
以二茂铁和纳米Ni粒子为催化剂,在水下放电争件下,制备了内包金属洋葱状富勒烯(Onion-like Fullerenes:OLFs),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:二茂铁和纳米Ni粒子均可催化得到内包金属洋葱状富勒烯,内包Fe洋葱状富勒烯直径分布在5~50nm之间,内包Ni洋葱状富勒烯直径分布在10~35nm之间。
Metal-encapsulated onion-like fullerenes (OLFs) are prepared with ferrocene and Ni as catalyst by arc-discharge in water. High resolution transmission electron mieroseopy(HRTEM) and X-ray diffraction(XRD) techniques are used to characterize the morphologies and structures of the products. Results indicate that metal encapsulated OLFs are produced by catalysis of ferrocene and Ni. Fe-eneapsulated OLFs have a diameter of 5~50nm. Ni-encapsulated OLFs have a diameter of 10~35nm.
