Embodiment 1

[0025] First, add the reactant precursor 0.64 g sulfur powder, 5.22 g tin tetrachloride pentahydrate, 10 g potassium hydroxide, and 20 mL deionized water into the reactor in sequence, and stir at room temperature for 5 min to the reactant precursor. Then the reaction kettle was sealed and placed in a vacuum oven at 200°C for 3 days, cooled to room temperature naturally, and finally washed and separated to obtain SnS. 2 Hexagonal nanosheets.

Embodiment 2

[0027] First, the reactant precursor 2.24 g sulfur powder, 10.52 g tin tetrachloride pentahydrate, 8 g potassium hydroxide, and 30 mL deionized water were sequentially added to the reaction kettle, and stirred at room temperature for 15 min to the reactant precursor Dissolve, then seal the reactor and put it in a vacuum oven at 230°C for 5 days, cool to room temperature naturally, and finally wash and separate the precipitate to obtain SnS 2 Hexagonal nanosheets.

Embodiment 3

[0029] First, add 1.25 g sulfur powder, 3.50 g tin tetrachloride pentahydrate, 15 g potassium hydroxide, and 40 mL deionized water into the reaction kettle in sequence, and stir at room temperature for 30 min to reach the reactant precursor Dissolve, then seal the reactor and put it in a vacuum oven at 190°C for 6 days, cool to room temperature naturally, and finally wash and separate the precipitate to obtain SnS 2 Hexagonal nanosheets.

Abstract

The invention discloses a method for preparing SnS2 hexagonal nanosheets by a hydrothermal process. The method comprises the following steps: sequentially adding a reactant precursor sulfur compound, soluble tin salt, strong alkali and deionized water into a reaction kettle, stirring at room temperature until the reactants are dissolved, sealing the reaction kettle, putting the sealed reaction kettle into a vacuum drying oven, reacting at 180-240 DEG C for 12 hours-10 days, and naturally cooling to room temperature; and finally, washing the separated precipitate to obtain the SnS2 hexagonal nanosheets. The method is simple to operate, and has no requirements for equipment. Various solvents are environment-friendly, so no high-toxicity substance is generated; and the method is low in cost, and is suitable for commercial production.

Description

Technical field [0001] The invention belongs to the field of materials science and relates to a method for preparing tin disulfide, specifically, a method for preparing SnS by hydrothermal method 2 Hexagonal nanosheet method. Background technique [0002] Energy is the foundation of economic development and the basic condition for human survival. With the rapid development of modern industry, the demand for energy is increasing. The use of conventional fossil energy will release a large amount of carbon dioxide and some harmful gases, which will cause serious damage to the environment. Therefore, changing the energy structure and looking for renewable energy has become the primary issue that all mankind must face. Renewable energy is the most effective way to replace conventional fossil energy. Renewable energy is roughly divided into wind energy, solar energy, geothermal energy, tidal energy, etc. Among the above-mentioned energy sources, solar energy has the most potential to...
