A simple biomolecule-assisted synthetic route has been successfully developed to prepare bismuth sulfide(Bi 2 S 3 ) nanorods under solvothermal conditions.In the synthetic system,pentahydrate bismuth nitrate was employed to supply Bi source and L-cystine was used as sulfide source and complexing agent.The morphology,structure,and phase composition of the as-prepared Bi 2 S 3 products were characterized by X-ray diffraction(XRD),energy dispersion spectroscopy(EDS),X-ray photoelectron spectroscopy(XPS),field-emission scanning electron microscopy(FESEM),transmission electron microscopy(TEM),selected area electron diffraction(SAED),and high-resolution transmission electron microscopy(HRTEM).The experimental results show that the nanorods have uniform diameter of 100-200 nm and length of 2-4 μm.The possible formation mechanism for the bismuth sulfide nanorods was discussed.

In the synthetic system, pentahydrate bismuth nitrate was employed to supply Bi source and L-cystine was used as sulfide source and complexing agent. The morphology, structure, and phase composition of the as-prepared Bi 2 S 3 products were characterized by X-ray diffraction (XRD), energy dispersion spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and high-resolution transmission electron microscopy (HRTEM). The experimental results show that the nanorods have uniform diameter of 100-200 nm and length of 2-4 μm. The possible formation mechanism for the bismuth sulfide nanorods was discussed.
