摘要

研究了氯化铁在单壁碳纳米管（SWCNTs）通道中的晶体结构。采用熔融法制备了直径为1.4 nm的混合电导率SWCNTs通道。在高分辨率透射电子显微镜（HRTEM）图像的基础上，模拟了包裹的氯化铁的晶体结构，并生成了TEM图像。结果表明，包封后的氯化铁具有不同于三维结构的一维结构，其空间群为\(R\bar {3}m\)，晶格参数为a = 3.5980 Å， c = 17.5360 Å。通过拉曼光谱研究了填充的SWCNTs。揭示了SWCNTs电子结构的修饰。所得数据对于填充SWCNTs在纳米电子学、催化、传感器、生物医学、电化学储能、自旋电子学、磁存储和磁记录等领域的应用具有重要意义。

Crystal Structure of Iron Chloride in Channels of Single-Walled Carbon Nanotubes

The crystal structure of iron chloride in channels of single-walled carbon nanotubes (SWCNTs) is investigated. The channels of SWCNTs with mixed conductivity and a diameter of ~1.4 nm are filled with iron chloride by means of the melt method. On the basis of high-resolution transmission electron microscopy (HRTEM) images, the crystal structure of the encapsulated iron chloride is modeled, and TEM images are produced. It is shown that the encapsulated iron chloride has a one-dimensional structure that differs from the three-dimensional structure with the \(R\bar {3}m\) space group and the lattice parameters a = 3.5980 Å and c = 17.5360 Å. The filled SWCNTs are investigated via Raman spectroscopy. Modification of the electronic structure of the SWCNTs is revealed. The obtained data are important for applying filled SWCNTs in nanoelectronics, catalysis, sensors, biomedicine, electrochemical energy storage, spintronics, magnetic storage, and magnetic recording.
