利用超声技术, 选择间二甲苯溶液和乙腈两种不互溶的溶剂, 首次成功地制备了C60的空心纳米壳. 选择扫描电镜(SEM), 透射电镜(TEM)等对所制得的C60的空心纳米壳的形貌及结构进行表征. C60空心纳米壳的外直径为300~400 nm, 内直径为200~300 nm, 壁厚约100 nm. X射线衍射光谱(XRD)、傅里叶红外光谱检测结果表明其为C60分子组成的单晶结构. 利用电泳方法制备了均匀的C60的空心纳米壳膜电极, 并利用电沉积方法在所制备的C60的空心纳米壳电极表面沉积了金(Au)纳米颗粒. 为进一步沉积其它金属, 研究其在生物传感器及燃料电池方面的应用提供了基础.

C60 hollow nanoshells were firstly prepared in a binary organic solution of m-xylene and acetonitrile by applying ultrasonication. The morphologies of C60 hollow nanoshells were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The outer diameter and inner diameter were 300~400 nm and 200~300 nm respectively, and the thickness of the wall was about 100 nm. The image of TEM certified that the sample took a hollow structure. XRD and FTIR spectrum results showed that the C60 hollow nanoshells were of a single crystalline structure and composed of pristine C60 molecules. The uniform C60 hollow nanoshell electrode was prepared by electrophoresis and the Au nanoparticles were then deposited by an electrochemical reduction method. The following depositions of other metals are continuing. The applications of these metal/C60 hollow nanoshell electrodes to the biosensors and fuel cells are being studied.
