Embodiment 1

[0025] Dissolve 0.245g of manganese acetate tetrahydrate in a mixed solution of 15mL of formamide and 15mL of water, then add 0.150g of thioacetamide, stir evenly, transfer to a stainless steel reaction kettle lined with polytetrafluoroethylene, at 180°C Under reaction for 24 hours. After the reactor was cooled to room temperature, the solid and liquid were separated, the solid was washed with water and ethanol in sequence, and finally the solid was dried at 80° C. to obtain manganese sulfide powder.

[0026] When the manganese sulfide is used as a capacitor electrode material, the specific capacitance is 512F / g.

Embodiment 2

[0028] Get 0.245g of manganese acetate tetrahydrate and dissolve it in a mixed solution of 15mL of triethylamine and 15mL of water, then add 0.232g of allylthiourea, stir evenly, move it into a stainless steel reaction kettle lined with polytetrafluoroethylene, The reaction was carried out at 180° C. for 10 hours. After the reactor was cooled to room temperature, the solid and liquid were separated, the solid was washed with water and ethanol in sequence, and finally the solid was dried at 70° C. to obtain manganese sulfide powder.

Abstract

The invention belongs to the technical field of chemical synthesis, and particularly relates to a preparation method of manganese sulfide. The method comprises the steps that (1), manganese acetate isdissolved in a solvent; (2), a sulfur source is added and stirred uniformly to conduct hydrothermal reaction; (3), solid and liquid are separated to obtain separated solid, and a product manganese sulfide is obtained after the solid is washed and dried. The method has the advantages that a preparation technology is simple, reaction conditions are mild, and the prepared manganese sulfide has goodmorphology and high purity.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a preparation method of manganese sulfide. Background technique [0002] Manganese sulfide (MnS) crystals usually have three isomers: α-MnS with rock salt structure, β-MnS with sphalerite structure and γ-MnS with wurtzite structure. β-MnS and γ-MnS are metastable phases, and when high temperature and high pressure are applied to them, they tend to form a green stable phase α-MnS. As a P-type semiconductor and antiferromagnetic material, MnS has a large bandwidth (Eg=3.7ev). It can be used as a window or buffer material for solar cells, and can improve the sensitivity of microcrystalline emulsions. It can form dilute with Cd and Zn. Magnetic semiconductor materials, dilute magnetic materials exhibit the composite properties of magnetic and semiconductor properties. At the same time, manganese sulfide, as an easy cutting agent, is also widely used in powder...
