1315-01-1 - Uses and methods of synthesis
Background
tin disulfide is an n-type semiconductor material, which has a layered hexagonal CdI2 crystal structure and a wide band gap of about 2.35eV, it can be used as a holographic recording and electrical conversion system material, a solar cell material, an anode material of a lithium-ion electronic battery, and the like. Because tin disulfide has a similar band gap with silicon, safety and environmental protection, absorption coefficient is also very high, so it is very suitable for the absorption layer of solar cells. In recent years, it has become a hot research topic of experts at home and abroad, it can also be used for imitation of gold plating and pigment.
Introduction
tin disulfate is a golden yellow crystal or a yellow amorphous solid. Industrial tin chips (or tin amalgam) and sodium sulfide, ammonium chloride to Yellow Yellow Flake crystals (dry), said color gold, hydrogen sulfide into the appropriate acidity of tin (IV) the salt solution gave a yellow amorphous precipitate (wet method). Are insoluble in water. Dissolved in aqua regia, alkali metal sulfide (generation of thiostannate), strong alkali (generation of thiostannate and hexahydroxystannate) and other solutions. The wet process product is soluble in warm, moderate concentrations of hydrochloric acid, whereas the dry process product is insoluble in hydrochloric acid.
apply
tin disulfide (SnS2) is a two-dimensional van der Waals semiconductor material with excellent photoelectric properties. The material is non-toxic, environmentally friendly, rich in content and easy to prepare. Tin sulfide properties for the semiconductor, mainly used in laboratory research and development, experiment, is currently very active in the market.
Application examples
tin disulfide can be used to prepare a tin bisulfate catalyst for the preparation of hydrogen for fuel cells, and to prepare a cobalt tetroxide-tin bisulfate nanocomposite, the preparation of a tin disulfate nanosheet composite material and the preparation of a carbon nitride/tin disulfate quantum dot composite photocatalyst relate to a photocatalyst.
preparation
by introducing hydrogen sulfide into the acid solution of tin tetrachloride, a bright yellow tin disulfide precipitate can be obtained by the action of sulfide on the tin chloride solution.
