在水热条件下，不使用任何添加剂，成功地合成了片状的SnS2纳米结构（如堆叠的纳米片和单独的纳米片）。实验参数，如反应温度和前体浓度，在确定最终产物的形貌和相的关键作用。此外，还根据成核动力学和晶体生长动力学的影响，讨论了SnS2纳米片的形成机理。电化学测试表明，SnS2纳米材料在锂离子电池中的电化学性能与其形貌有关，合成的SnS2纳米材料有望在锂离子电池中得到应用。
Plate-like SnS2 nanostructures (such as stacked nanoplates and individual nanoplates) have been successfully synthesized under hydrothermal conditions without using any additive. Experimental parameters, such as reaction temperature and precursor concentration, play crucial roles in determining the morphologies and phase of final products. Furthermore, the formation mechanism of the stacked SnS2 nanoplates has also been discussed, based on the influence of the kinetics of nucleation and crystal growth. Morevoer, electrochemical measurements indicate the morphology-depending electrochemical properties of SnS2 materials in the application of lithium-ion batteries and the synthesized SnS2 nanomaterials could be expected to be potentially used in lithium ion batteries.
