在聚乙烯吡咯烷酮(PVP)或丙酮存在下，用乙二醇还原铋钠可选择性地制备单晶铋纳米线和纳米球。通过改变一些反应参数，还可以得到铋纳米带和Bi/Bi2O_3纳米晶。用X射线衍射仪、X射线能谱分析、扫描电子显微镜、透射电子显微镜、高分辨电子显微镜和傅立叶变换红外光谱等技术研究了这些低维铋纳米结构的物理特性。
A facile solution-phase process has been demonstrated for the selective preparation of single-crystalline bismuth nanowires and nanospheres by reducing sodium bismuthate with ethylene glycol in the presence of poly(vinyl pyrrolidone) (PVP) or acetone. Bismuth nanobelts and Bi/Bi2O3 nanocables could be also obtained by changing some reaction parameters. Various techniques such as XRD, EDXA, SEM, TEM, HRTEM, and FT-IR have been used to investigate the physical characteristics of these low-dimensional bismuth nanostructures.
