以L-胱氨酸为硫源,采用溶剂热法在不同的溶剂中反应,制备出硫化铋(Bi2S3)纳米薄片和纳米棒,采用X射线衍射(XRD)仪、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等分别对所合成的Bi2S3晶型结构、表面形貌进行表征。结果表明,所合成的Bi2S3为典型的Bi2S3正交结构。以DMF为溶剂,在160℃下反应5d,得到了长为4000～8000nm、宽为200～300nm的正交相Bi2S3纳米棒。根据实验结果对所合成的Bi2S3的形成机制进行简单探讨。 (Bi2S3) nanoflakes and nanorods were prepared by solvothermal method using L-cystine as the sulfur source and solvothermal method. X-ray diffraction (XRD) and scanning electron microscopy (SEM) Transmission electron microscopy (TEM), respectively, the synthesized Bi2S3 crystal structure, surface morphology was characterized. The results show that the synthesized Bi2S3 is a typical Bi2S3 orthorhombic structure. DMF was used as a solvent and reacted at 160 ℃ for 5 days to obtain Bi2S3 nanorods with phase length of 4000-8000 nm and width of 200-300 nm. Based on the experimental results, the formation mechanism of Bi2S3 was briefly discussed.
