摘要
文章以乙二醇为溶剂、硫代乙酰胺(TAA)为硫源、按文献报道的方法制备的单质铋纳米管阵列作为前驱体并作为自牺牲模板,通过常压沸腾回流法大规模合成了硫化铋单晶纳米棒。采用X-射线多晶粉末衍射仪(XRD)、透射电子显微镜(TEM)、场发射扫描电子显微镜(FESEM)和高分辨透射电子显微镜(HRTEM)等测试技术对所制备样品的结构和形貌进行了表征。结果表明样品为纯相正交晶型,直径30~60纳米,长达数微米。
Single-crystal Bismuth sulfide nanorods were synthesized on a large scale by a rapid glycol refluxing process, using thiacetamide(TAA) as sulphur source and the prepared bismuth nanotube arrays as the precursors. XRD, TEM, SEM and HRTEM characterizations show that the as-prepared Bi2S3 samples are all phase pure and the Bi2S3 nanorods have uniform diameters of approximately 3060 nm and lengths up to several micrometers.
