What is Tin disulfide

What exactly is Tin disulfide?

Tin disulfide is an organic compound that has the chemical formula SnS2. It is a yellow hexagonal flake with it's CdI2 crystal shape. It isn't very soluble water, however it's soluble in aqua regia , and hot alkaline solution. It is can be found in sodium sulfide Solution, commonly used as golden paint.

Tin disulfide dissolves in aqua regia and hot acid solution. It also undergoes coordination reaction when combined with concentrated hydrochloric acid. However, it's dissolvable in dilute hydrochloric acids that is insoluble with water and the acid nitric. It can also react with ammonium sulfide to dissolve.

How do you make Tin disulfide?

Tin disulfide can be obtained simply by combining tin directly with sulfur in the presence of Iodine. The reaction involves heating:

2. S -- SnS2

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

Electrochemical behavior of multi-walled carbon Nanotubes, confined by tin disulfide. It is the negative electrodes in lithium ion battery

Direct current arc-plasma method was used to prepare multi-walled carbon nanotubes-confined metal tin nanostructures (Sn@MWCNT) as an intermediate in a methane-based atmosphere. SnS_2@MWCNT nanostructures were obtained through the process of sulfurization. The results of the physical characterization of the material , such as Raman, Xray diffraction (XRD), and the transmission electron microscope (TEM) proved that the size of multi-walled carbon Nanotubes measured around 400nm. Furthermore, the surfaces of the carbon layer were well crystallized in addition, the thickness of this carbon-based layer was around 10 nm. Lithium-ion cells using Sn S2@MWCNT nanostructures for anodes materials exhibit a decent electrochemical performance. The first recharge Coulomb performance is 71%, in the course of 50 cycle, the battery's capacity remains stable at 703 mAh?g-1. The superior capacity characteristics of SnS_2@MWCNT nanostructured electrodes stem from the fact that various types of active materials offer the capacity of the two together. The reaction platform of each is unique to each material.

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

A novel composite material made of SnS2 with single-walled carbon Nanotubes (SWCNTs) has been prepared using a simple solvothermal method. It was found to have excellent electrochemical characteristics after being placed on the electrode that is negative of the lithium ion battery. In a high density of current of 1 A/g hundred cycles it still retains a reversible capacity of 510 milliamps per gram. In order to compare, we applied this same method to create a single SnS2 material and conduct an electrochemical analysis on it. Results show that even though the initial specific performance of SnS2 material is rather excellent, the cycle efficiency is poorand goes through a rapid decline after less than 20 cycles. The superior efficiency of the composite in batteries made from lithium is believed to be due to its synergy with the two substances of SnS2 along with SWCNTs.
