摘要：

Copper sulfide-core/carbon-shell cables and spheres have been prepared by a simple hydrothermal method. The obtained CuS/C cables and spheres were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman, Fourier transform infrared spectroscopy, photoluminescence, and UV-vis-NIR spectrum analysis. The resulting CuS/C cables and spheres were obtained by a hydrothermal process in the presence of beta-cyclodextrin (beta-CD) acting as the ligand and the carbon source of the sheath. The influence of the reaction time, reaction temperature, different sulfur source, and different solution system on the final products was investigated in detail. The possible formation mechanism for these copper sulfide-core/carbon-shell cables was also proposed. Moreover, by using hot hydrochloric acid to dissolve the CuS cores, amorphous carbon nanotubes and hollow nanospheres can be obtained..
