Two preparation methods of tin sulfide SnS2 powder

Preparation method of tin disulfide SnS2

Tin disulfide can be obtained by directly combining tin and sulfur in the presence of iodine. The reaction requires heating:

Sn + 2S —→ SnS2

Another method is to pass hydrogen sulfide into the tin (IV) salt or tin (IV) salt solution and precipitate it.

Overview of tin sulfide SnS2 powder

Tin disulfide is an inorganic compound with the chemical formula SnS2. It is a yellow hexagonal flake with the crystal structure of CdI2. It is almost insoluble in water, soluble in aqua regia and hot alkali solution, and also soluble in sodium sulfide solution. It is usually used to make golden paint.

Tin (IV) sulfide crystallizes in the form of cadmium iodide precursor crystals, where Sn(IV) is located in an "octahedral pore" defined by six sulfide centers. It naturally appears as a rare mineral montmorillonite, which can be used as a semiconductor material with a band gap of 2.2 eV.

SnS2 tin sulfide is an n-type semiconductor material with a hexagonal CdI2 structure. Tin disulfide (SnS2) is a layered metal dihalide semiconductor with a chemical and crystal structure similar to molybdenum disulfide (MoS2). In each individual layer, Sn is sandwiched between two Slayers with strong covalent bonds, while a single monolayer is maintained by weak van der Waals forces. When the weak van der Waals force is overcome by physical or chemical peeling, each layer will break freely.

Like many other two-dimensional semiconductors, SnS2 is stripped to form an atomic layer sheet, which can be used in FET, photovoltaic solar cells, sensors, and photocatalyst applications.

Tin disulfide is an acid sulfide, soluble in aqua regia and hot alkali solution, and can undergo coordination reaction with concentrated hydrochloric acid, but is insoluble in dilute hydrochloric acid, water and nitric acid. It can react with ammonium sulfide to dissolve.

Application of SnS2 tin sulfide powder

Tin disulfide (SnS2) is a two-dimensional van der Waals semiconductor material with excellent optoelectronic properties. The material is non-toxic, environmentally friendly, rich in content and easy to prepare. The nature of tin sulfide is a semiconductor, which is mainly used for laboratory research, development and experimentation, and is currently very active in the market.

Tin disulfide is an n-type semiconductor material with a layered hexagonal CdI2 crystal structure and a wide band gap of approximately 2.35 eV. The wide band gap makes it have good photoelectric properties, which can be used as materials for holographic recording and electrical conversion systems, materials for solar cells, and anode materials for lithium chemical book batteries.

Because SnS2 tin sulfide powder has a band gap similar to that of silicon, it is safe and environmentally friendly, and has a high absorption coefficient, making it very suitable for use as an absorber layer for solar cells. In recent years, it has become a hot spot for domestic and foreign experts. It can also be used for imitation gold plating and manufacturing. Used for paint etc.

Tin disulfide single crystals can be used to prepare single and multilayer SnS2 by mechanical or liquid stripping.

Tin disulfide powder is suitable for liquid chemical exfoliation to prepare SnS2 nanosheets and nanoparticles with as few layers as thin films.

Tin disulfide has high sensitivity and high surface activity. Exfoliated SnS2 single-layer or multilayer ultra-thin films made of bulk crystals and powder have also been used in light emitters, field effect transistors (FET), gas sensors and photodetectors. Thermoelectric photovoltaics and other fields as well as the application of lithium-ion batteries in energy storage equipment.
