通过在反应体系中引入不同的有机络合剂或离子液体，成功地实现了尺寸和形状可控的Sb2S3纳米结构的合成。通过引入不同的有机络合剂或离子液体，可以得到一维纳米棒、二维纳米束、三维束状超结构、哑铃状超结构和海胆状微球等多种纳米结构。根据Sb2S3纳米结构的晶体结构和络合剂的性质以及离子液体的性质，合理地提出了各种Sb2S3纳米结构的形成机理。此外，还详细讨论了实验参数对最终产物的影响。电化学测试表明，合成的Sb2S3纳米结构具有较高的初始嵌锂容量和优异的循环性能，表明所合成的Sb2S3纳米结构在商业电池中具有潜在的应用前景
The size and shape con trolled synthesis of Sb2S3 nanostructures has been successfully realized by a facile hydrothermal route A range of dimensional nanostructures, such as one-dimensional nanorods two dimensional nanowire bundles three dimensional sheaf-like superstructures, dumb bell-shaped superstructures, and urchin like microspheres, could be obtained through introducing different organic complex reagents or ionic liquids to the reaction system The formation mechanisms of various Sb2S3 nanostructures have been rationally proposed based on the crystal structure and the nature of the complex reagents and the ionic liquid The effects of experimental parameters on the final product are also discussed in detail In addition, electrochemical measurements demonstrate that the as synthesized Sb2S3 nanostructures have higher initial Li intercalation capacity and excellent cyclic performances which indicates that the as-synthesized Sb2S3 nanostructures could have potential applications in commercial batteries
