Problems solved by technology

Although this method can obtain the target product in a relatively short period of time, the tin disulfide used needs to be treated in a vacuum quartz tube for a week at a temperature of 923-823K to make it into a single crystal state. Further purification is required, and all post-processing operations must be performed in a dry glove box, which requires high equipment

Abstract

The invention discloses a preparation method of an ethanediamine intercalation tin sulfide compound. The preparation method comprises the following steps: putting tin sulfide and absolute ethyl alcohol in a polytetrafluoroethylene inner cylinder, slowly adding anhydrous ethanediamine, and then evenly stirring; tightening a reaction kettle, putting the reaction kettle in a muffle furnace, and regulating the temperature to 150-180 DEG C for 20-24 hours; and after the reaction is finished, centrifuging so as to obtain the solid substance ethanediamine intercalation tin sulfide compound. The preparation method is simple, and the obtained product is high in purity; and ethanediamine molecules enter into gaps of tin sulfide, thereby enlarging the interlamellar spacing of a layered material, improving the property of an inorganic material and broadening the application range of the inorganic material.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis materials, in particular to a preparation method of ethylenediamine intercalation tin disulfide compound. Background technique [0002] The remarkable feature of layered compounds is that they can be used as hosts, allowing the entry of molecules, ions and other guests, so as to obtain intercalation compounds with improved physical properties. Since the 1970s, a great deal of research has been done on intercalation compounds, however, most of the research has focused on transition metal layered materials and strongly reducing guests. 2 Crystalline SnS 2 The intercalation of layered materials and weakly reducing organic amine compounds is less studied. [0003] In the ethylenediamine molecule, there are unshared electron pairs on the nitrogen atom, so it belongs to the Lewis base and has certain reducing properties. At the same time, ethylenediamine is a chain-like organic molecule. As...
