摘要:

以SbCl3L-胱氨酸为反应原料, 采用溶剂热法在170 ℃反应12 h, 制得硫化锑(Sb2S3)纳米棒. X射线衍射(XRD)、能量分散光谱(EDS)和X射线光电子能谱(XPS)研究表明所得产物为典型的Sb2S3正交结构. 场发射扫描电子显微镜(FESEM)和透射电子显微镜(TEM)研究显示, Sb2S3纳米棒长为3~6 μm, 平均直径约为150 nm. 讨论了不同反应时间对Sb2S3的形成及其形貌的影响, 并根据实验结果对所合成的一维纳米棒可能的形成机理进行了简单的探讨.

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.
