C_(60)空心纳米壳的制备及研究

摘要

C_(60) hollow nanoshells were firstly prepared in a binary organic solution of m-xylene and ace-tonitrile by applying ultrasonication.The morphologies of C_(60) 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 C_(60) hollow nanoshells were of a single crystalline structure and composed of pristine C_(60) molecules.The uniform C_(60) 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/C_(60) hollow nanoshell electrodes to the biosensors and fuel cells are being studied.%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C_(60)的空心纳米壳.选择扫描电镜(SEM),透射电镜(TEM)等对所制得的C_(60)的空心纳米壳的形貌及结构进行表征.C_(60)空心纳米壳的外直径为300～400nm,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C_(60)分子组成的单晶结构.利用电泳方法制备了均匀的C_(60)的空心纳米壳膜电极,并利用电沉积方法在所制备的C_(60)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.
