水下放电制备内包金属洋葱状富勒烯的研究

Study of Preparation of the Metal-encapsulated Onion-like Fullerenes by Arc Discharge in Water

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.
