| 摘 要： | Sn-filled carbon nanotubes(CNTs) were prepared in situ by electrolysis of graphite in molten LiCl/SnCl2 mixtures. Transmission electron microscopy(TEM) investigation shows that the as-made products contain abun-dance of carbon nanotubes and most of them are filled with metal nanoparticles or nanorods. Some nanotubes are e-ven inserted with long continuous nanowires more than several micrometers in length. Selected area electron diffrac-tion(SAED) patterns and energy dispersive X-ray spectroscopy(EDS) of the filled nanotubes confirm the presence of Sn inside the nanotubes. The encapsulated Sn was further identified as β-Sn with tetragonal structure. Based on the experimental results, a possible growth mechanism of the Sn-filled nanotubes was also discussed.

| Abstract: | Sn-filled carbon nanotubes(CNTs) were prepared in situ by electrolysis of graphite in molten LiCl/SnCl2mixtures. Transmission electron microscopy(TEM) investigation shows that the as-made products contain abundance of carbon nanotubes and most of them are filled with metal nanoparticles or nanorods. Some nanotubes are even inserted with long continuous nanowires more than several micrometers in length. Selected area electron diffraction(SAED) patterns and energy dispersive X-ray spectroscopy(EDS) of the filled nanotubes confirm the presence ofSn inside the nanotubes. The encapsulated Sn was further identified asβ-Sn with tetragonal structure. Based on theexperimental results, a possible growth mechanism of the Sn-filled nanotubes was also discussed. |
