Abstract

The synthesis of copper sulfide carbon nanotubes and nanobelts using lyotropic nonionic-anionic mixed-surfactant liquid crystal acting as soft template was analyzed. Powder X-ray diffraction (XRD) measurements were performed on Philips X'Pert MPD Pro X-ray diffractometer with graphite monochromatized Cu K∞ radiation, operating at 50kV. Transmission electron micrographs (TEM) were taken on a JEM-100S Electron Microscope (JEOL), using an accelerating voltage of 80kV. Nanotubes were formed by the condensation mechanism of anionic surfactants and the non ionic surfactant Tween 40 was essential to stabilize the ion pairs and bring out the lamellar assembly. The typical morphologies of the prepared samples were characterized by TEM technique. The results show that the precursor for CuS nanotubes is in a sheet like morphology, and the precursors for CuS nanobelts synthesized from CuCl 3 and thioacetamide is in a belt like morphology.
