SnS2 nanobelts were successfully synthesized through a controllable solution-phase hydrothermal method on a large scale. The nanobelts have a very high yield, which is more than 95%, with widths ranging from 100 to 200 nanometers, lengths up to several micrometers and thicknesses ca. 10 nanometers. X-ray diffraction patterns, electronic diffraction, X-ray photoelectron spectra, field emission scanning electron microscopy images, transmission electron microscopy images and high-resolution transmission electron microscopy investigated the phase structures, compositions, and morphologies of SnS2 nanobelts. Dodecanethiol played important roles in the process of SnS2 nanobelts formation and growth. The formation mechanism of SnS2 nanobelts was investigated and discussed on the basis of the experimental results.
通过可控的溶液相水热法成功地大规模合成了二硫化锡纳米带。这些纳米带的产率非常高，超过95%，宽度在100到200纳米之间，长度可达几微米，厚度约为10纳米。通过X射线衍射图谱、电子衍射、X射线光电子能谱、场发射扫描电子显微镜图像、透射电子显微镜图像和高分辨率透射电子显微镜对二硫化锡纳米带的相结构、组成和形态进行了研究。十二烷硫醇在二硫化锡纳米带的形成和生长过程中起重要作用。基于实验结果对二硫化锡纳米带的形成机理进行了研究和讨论。
