What is Tin disulfide?
Tin disulfide (also known as Tin) is an inorganic compound with a chemical formula of SnS2. It is a yellow hexagonal flake containing the CdI2 crystal form. It isn't really soluble in the water, but it's easily soluble in aqua regia as well as hot alkaline solutions. It's additionally, it is soluble in sodium sulfur Solution, which is often used as gold paint.
Tin disulfide is soluble hot alkali and in aqua regia solution. It is also able to undergo coordination reactions when exposed to concentrated hydrochloric acid. It is imsoluble within dilute hydrochloric acid and insoluble when mixed with water and in nitric acid. It can also react with ammonium sulfide to dissolve.
How do I make tin disulfide?
Tin disulfide can be made via direct fusion of tin and sulfur with iodine. The reaction requires heat:
Sn + 2 S -- SnS2
Another approach is to inject hydrogen sulfide in the solution of either tin (IV) salt and tin (IV) salt solution to melt it.
Electrochemical properties of multi-walled carbon Nanotubes, confined to tin dioxide as the negative electrode in lithium ion battery
Direct current arc-plasma method was used to make multi-walled carbon nanotubes-confined metal tin nanostructures (Sn@MWCNT) as the precursor under a methane atmosphere, and then SnS_2@MWCNT was obtained by an sulfurization process. The results of the physical characterisation of the materials such as Raman, Xray diffraction (XRD) and Transmission electron Microscopy (TEM) proved that the length of the multi-walled carbon nanotubes was around 400nm. In addition, the surface carbon layer was crystallized with the thickness of carbon being around 10 nanometers. Lithium-ion batteries made of Sn S2@MWCNT nanostructures as anode materials have an impressive electrochemical performance. The initial charge-discharge Coulomb efficiency is 71%, in the course of 50 cycle, this capacity is still at 703 mAh?g-1. The high-capacity properties of SnS_2@MWCNT nanostructured electrodes come from the fact that a wide range of active materials can provide the capacity together, and the reaction platform of each material differs.
Study on electrochemical performance of tin disulfide/single-walled carbon nanotube composite material used as anode material for lithium-ion battery
A new composite material composed of SnS2 with single-walled carbon Nanotubes (SWCNTs) was created using an easy solvothermal procedure. It is found to have good electrochemical performance after being placed on the electrode that is negative material of lithium ion battery. In a high density of current of 1 A/gand after 100 cycles, it keeps a reversible reversible particular capacity of approximately 510 mAh/g. In order to compare, we applied the same method to synthesize a single SnS2 material and conducted electrochemical tests on it. The results reveal that while the initial ability of SnS2 material is relatively good, its cycle performance is poorand decreases rapidly after less than 20 cycles. The superior quality of this material for lithium-ion batteries thought to be due to its synergy with the two parts made up of SnS2 along with SWCNTs.
