Tin Disulfide Powder and Crystal
Low price, high purity 2D metal tin disulfide powder and crystals
Tin disulfide (SnS2) is a layered metal dichalcogenide semiconductor with a similar chemical and crystal structure to that of molybdenum disulfide (MoS2). In each individual layer, Sn is sandwiched between two S layers with strong covalent bonding, whereas individual mono-layers are held by weak van der Waals forces. Individual layers break free when weak van der Waals forces are overcome by either physical or chemical exfoliation.
Like many other two dimensional semiconductors, SnS2 can undergo exfoliation to form atomic-layer sheets that have applications in FETs, photovolatic solar cells, sensors and photocatalyst applications.
SnS2 is an n-type semiconducting material that has a hexagonal CdI2-type structure.

Structure and Properties of 2D Tin Disulfide
After exfoliation of crystals or powder, tin disulfide typically has the following properties:
- Hexagonal (2H) structure (space group: P3m1)
- Earth-abundant, non-toxic, and chemically stable
- n-type semiconducting material with band-gap of 2.2–2.35 eV
Applications of Tin Disulfide
Tin disulfide single crystals can be used to prepare monolayer and few-layer SnS2 by mechanical or liquid exfoliation. Tin disulfide powder is suitable for liquid chemical exfoliation to prepare SnS2 nanosheets and nanoparticles down to few-layer films.
With high sensitivity and high surface activity, exfoliated SnS2 single or few-layer ultra-thin films from bulk crystal and powder have also been used in applications ranging from light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric photovoltaic and energy storage devices such as for applications Li-ion batteries

Structure of Tin Disulfide
Tin disulfide (SnS2) has a layered structure, where each Sn ion coordinates to six S ions in a regular octahedron. Each sheet of Sn atoms is sandwiched between two sheets of S atoms, and each S-Sn-S layer is held by weak van de Vaals interactions.
SnS2 crystallises with a standard hexagonal crystal structure (2H-SnS2) which is identical to that of 1T-MoS2. Monolayers of 2H-SnS2 are stacked precisely on top of one another to form the 2H-polytype of bulk SnS2. It is noted that the 2H-SnS2 structure is different from that of 2H-MoS2, where the Mo atom possesses a trigonal prismatic coordination instead.
Applications of Tin Disulfide
With a band-gap of 2.2–2.35 eV, hexagonal SnS2 has been used for efficient visible-light water-splitting. It is earth-abundant, non-toxic, and chemically stable in both acidic or neutral aqueous solutions. Physical or liquid exfoliated SnS2 single or few-layer ultra-thin films from bulk crystal and powder have also been used in applications ranging from light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric photovoltaic and energy storage devices
