What is tin disulfide?

Tin disulfide is an inorganic compound with the chemical formula SnS2. It is a yellow hexagonal flake with a CdI2 crystal structure. It is hardly soluble in water, soluble in aqua regia and hot alkali solution, and also soluble in sodium sulfide solution. It is often used as a gold paint. Tin disulfide is soluble in aqua regia and hot alkali solution, and can undergo coordination reaction with concentrated hydrochloric acid, but it is insoluble in dilute hydrochloric acid, insoluble in water and nitric acid. It can also react with ammonium sulfide to dissolve.

How to prepare tin disulfide?

Tin and sulfur can be directly combined in the presence of iodine to obtain tin disulfide. The reaction requires heating:

Sn + 2 S —→ SnS2

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

Electrochemical behavior of multi-walled carbon nanotube confined tin disulfide as the anode of lithium ion battery

The direct current arc plasma method was used to prepare multi-walled carbon nanotube-confined metal tin nanostructures (Sn@MWCNT) as a precursor in a methane atmosphere, and then SnS_2@MWCNT nanostructures were obtained through the sulfurization reaction. The physical characterization results of the material such as Raman, X-ray diffraction (XRD), and transmission electron microscope (TEM) show that the length of multi-walled carbon nanotubes is about 400 nm, the surface carbon layer is well crystallized, and the thickness of the carbon layer is about 10 nm. Lithium-ion batteries using Sn S2@MWCNT nanostructures as anode materials exhibit good electrochemical performance. The first charge-discharge coulombic efficiency is 71%, and the capacity remains 703 mAh?g-1 after 50 cycles.

Study on the electrochemical performance of tin disulfide/single-walled carbon nanotube composite as anode material for lithium ion battery

A novel composite of SnS2 and single-walled carbon nanotubes (SWCNTs) was prepared by a simple solvothermal method. It is found that it has good electrochemical performance after being applied to the negative electrode material of lithium ion battery. At a high current density of 1 A/g, after 100 cycles, it still maintains a reversible specific capacity of 510 mAh/g. For comparison, we synthesized a single SnS2 material using the same method and performed electrochemical tests on it. The results show that although the initial specific capacity of SnS2 material is higher, the cycle performance is poor, and it decays quickly after 20 cycles. The excellent performance of this composite material in lithium-ion batteries is believed to be the result of the synergistic effect of the two components of SnS2 and SWCNT.

Overview of tin sulfide powder

Tin disulfide is an inorganic compound with the chemical formula SnS2. It is a yellow hexagonal flake crystal 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 tin (IV) is located in "octahedral pores" 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 acidic 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.

Uses 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 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 photovoltaic and other fields, as well as the application of lithium-ion batteries in energy storage equipment.
