Problems solved by technology

However, tin disulfide nanomaterials prepared by hydrothermal method and microwave irradiation method are mostly materials with large size, serious agglomeration and irregular shape, and some are even micron-scale materials, which is not conducive to product shape control; However, the output of microemulsion synthesis is very small, which is not conducive to the practical application of materials; the alumina template method requires prefabricated templates, resulting in increased costs

Embodiment 1

[0015] ①In a 100mL flask, add 0.4mmol of tin tetrachloride pentahydrate and 5mmol of hexadecylamine to 39.3mL of anisole, heat to 60°C and keep for 30 minutes until completely dissolved, then add 0.7mL of carbon disulfide , while adding, continue magnetic stirring to prepare a reaction solution of tin disulfide.

[0016] ②Put the reaction solution prepared according to step ① into a high-pressure reactor with a 50mL polytetrafluoroethylene liner. After reacting at 180°C for 24 hours, the reactor is naturally cooled to 60°C. After centrifugation, wash with absolute ethanol Several times, the sample is vacuum-dried to obtain hexagonal tin disulfide nanosheets.

[0017] The X-ray diffraction pattern of the tin disulfide nanoplate of gained hexagonal shape is as attached figure 1 shown. Depend on figure 1 It can be seen that all the diffraction peaks are completely consistent with the standard hexagonal SnS 2 Structure (JPCDS NO.23-677), belonging to P-3ml space group, its uni...
