Abstract:

A simple biomolecule-assisted synthetic route has been successfully developed to prepare antimony sulfide(Sb2S3) nanorods at 170 ℃ for 12 h. In this synthetic system, antimony chloride(SbCl3) is employed to supply antimony source and L-cystine is used as sulfide source. X-ray powder diffraction(XRD), energy dispersion spectroscopy(EDS) and X-ray photoelectron spectroscopy(XPS) results indicate that the as-prepared powder is pure orthorhombic Sb2S3. Field-emission scanning electron microscopy(FESEM) and transmission electron microscopy(TEM) show that the Sb2S3 nanorods have an average diameter of 150 nm and length ranging from 3 to 6 μm. The effect of reaction time on morphology of the product has been investigated, and a possible formation mechanism for the antimony sulfide nanorods was also discussed.
