What is Tin disulfide

What exactly is Tin disulfide?

Tin disulfide is a non-organic compound with chemical formula SnS2. It is an orange hexagonal flake with its CdI2 crystal structure. It isn't soluble in water, but it's liquid in aqua regia and hot alkaline solutions, and also in sodium sulfide Solution, commonly used for gold paint.

Tin disulfide is soluble the alkali in hot and aqua regia solution. It also undergoes coordination reaction with concentrated acid. However, it is imsoluble within dilute hydrochloric acids as well as insoluble in water and in nitric acid. It is also capable of resolving with ammonium Sulfide to dissolve.

How do you make Tin disulfide?

Tin disulfide may be obtained through the direct combination of tin with sulfur with iodine. The reaction requires the heating process:

2. S -- SnS2

Another option is to pour hydrogen sulfide into solution of tin (IV) salt or tin (IV) salt solution, and then the precipitate.

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

Direct current arc plasma method was used to make multi-walled carbon nitrotube-confined metallic tin nanostructures (Sn@MWCNT) as the precursor under a methane environment, and later SnS_2@MWCNT-like nanostructures were fabricated by their sulfurization reactions. The results of physical characterization of the materials such as Raman, X-ray Diffraction (XRD) as well as the transmission electron microscope (TEM) demonstrated that the length of multi-walled carbon-carbon nanotubes was 400nm. The top layer of carbon was crystallized in addition, the thickness of this carbon-based layer was 10 nm. Lithium-ion-based batteries using Sn S2@MWCNT nanostructures as anode materials have relatively good electrochemical performance. The initial charge-discharge Coulomb performance is 71% with 50 cycles, it still maintains 703 mAh?g-1. The superior capacity characteristics of SnS_2@MWCNT nanostructured electrodes come from the fact that a wide range of active materials offer the capacity in combination, and the catalyst for each of them is different.

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

A novel composite of SnS2 combined with single-walled carbon nanotubes (SWCNTs) was developed using an easy solvothermal process. It is found to have an excellent electrochemical performance when put on to negative electrode material of the lithium Ion battery. When the current density is high of 1 A/gand after hundred cycles it keeps a reversible reversible particular capacity of approximately 510 mg/g. As a comparison, we used the same process to synthesize one SnS2 material and then conduct experiments on its electrochemistry. The results show that although the initial specific capabilities of SnS2 material is excellent, the cycle efficiency is low and decays quickly after less than 20 cycles. The higher performances of this compound in lithium-ion batteries are thought to be due to it being a synergy between both elements of SnS2 as well as SWCNTs.
