Abstract
A nanocomposite of antimony sulfide Sb2S3 embedded into the channels of single-walled carbon nanotubes (SWCNTs) has been prepared for the first time by the capillary wetting method and has been characterized by X-ray powder diffraction, transmission electron microscopy (TEM), transmission scanning electron microscopy (TSEM), and X-ray energy dispersive (EDX) spectroscopy. Antimony sulfide fills the channels of almost all SWCNTs. Channel filling is continuous along the entire length of the tube up to 1 μm. The diameters of filled SWCNTs fall in the range 0.6–3.5 nm. The periodicity of Sb2S3 crystal clusters observed on electron microscopic images is 2.0–2.2 nm along the nanotube axis and 2.5–3.5 nm in the transverse direction. A structural model of a Sb2S3 cluster is suggested.
