What is Tin disulfide

What's Tin disulfide?

Tin disulfide is an inorganic compound with the chemical formula SnS2. It is a yellow hexagonal flake containing the CdI2 crystal shape. It is hardly soluble in water, however, it is water-soluble in aqua regia. It is also soluble in hot alkaline solution. It's also soluble in sodium sulfide Solution, which is commonly used as golden paint.

Tin disulfide dissolves in aqua regia as well as hot alkali solution. It may undergo coordination reaction when combined with concentrated hydrochloric acid. However, it's insoluble in dilute hydrochloric acids and is insoluble in water and Nitric acid. It may also react with ammonium sulfur to dissolve.

How do you prepare Tin disulfide?

Tin disulfide can be made by combining directly tin with sulfur with iodine. The reaction requires the heating process:

2. S -- SnS2

Another method is to pass hydrogen sulfide in the tin (IV) salts, also known as tin (IV) salt solution, and then melt it.

Electrochemical behavior of carbon nanotubes with multi-walled walls confined tin disulfide as negative electrodes of lithium ion battery

The direct current arc plasma technique was used to prepare multi-walled carbon nanotubes-confined metal tin Nanostructures (Sn@MWCNT) as the precursor in methane atmosphere. Then, SnS_2@MWCNT were made by an sulfurization process. The results of physical characterization of the substance, including Raman, X-ray Diffraction (XRD) as well as the transmission electron microscope (TEM) confirmed that the length of multi-walled carbon nanotubes was approximately 400nm, the carbon layer on the surface was well crystallized, while the size of the carbon layer was 10 nm. Lithium-ion batteries made of Sn S2@MWCNT nanostructures as anode materials have relatively good electrochemical performance. The first charged-discharge Coulomb performance is 71% After 50 cycles, the power remains at 703 mAh?g-1. The characteristics of high-capacity SnS_2@MWCNT nanostructured electrodes are due to the fact that a range of active materials have the capacity to work together, and also the chemical reaction platform for each one is distinct.

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

A novel composite made up of SnS2 combined with single-walled carbon nanotubes (SWCNTs) was prepared by the simple solvothermal method. It is found to have excellent electrochemical characteristics after being added to the negatively electrode material of the lithium Ion batteries. In a high density of current of 1 A/gand after 100 cycle, it maintains a reversible specific capacity of about 510 milliamps per gram. To illustrate, we applied the same technique to make a single SnS2 material and then conduct studies on electrochemistry on the material. The results reveal that while the initial ability of SnS2 material is relatively high, its cycle performance is low and goes through a rapid decline after less than 20 cycles. The higher quality of this material for lithium-ion batteries thought to be the result of the synergy that occurs between the two components in SnS2 in addition to SWCNTs.
