Low price, high purity 2D metal titanium(IV) sulfide powder and crystals

For the development of next-generation electronics, optoelectronics, and nanotechnology

Titanium(IV) sulfide (also known as titanium disulfide TiS2) is highly stable. It is the most lightweight and low-cost Group IV TMDC material. TiS2 is known to be a semimetal in when in bulk form with an indirect band-overlap of about 0.12 eV, and a semiconductor when strain or pressure is applied in the monolayer form. With a higher degree of overlap of the valence and conduction bands, its semi-metallic nature intensifies when compression is applied. However, the energetic overlap is lifted and a semimetal-to-semiconductor transition occurs under pressure or strains.

Different Forms of Titanium(IV) Sulfide

TiS2 crystallises in an octahedral (1T) phase, which is more energetically stable compared to its hexagonal (2H) phase. Titanium(IV) sulfide has been successfully employed as an electrode material for rechargeable sodium and lithium ion batteries.

We supply low price titanium(iv) sulfide in several different forms for a range of applications.

Titanium(IV) sulfide powder can also be used to prepare TiS2 nanosheets and nanoparticles by liquid-exfoliation (normally assisted by sonication).

Key Product Data

Structure of Titanium(IV) Sulfide

A single sheet of TiS2 is formed by a titanium atom layer sandwiched between two layers of sulfur atoms that are covalently bonded to the titanium atoms. Like other Group IV transition metal dichalcogenides, TiS2 crystallises in an octahedral (1T) phase, which is more energetically stable compared to its hexagonal (2H) phase.

Properties of 2D Titanium(IV) Sulfide

After exfoliation of crystals or powder, titanium(IV) sulfide typically has the following properties:

  • Hexagonal (1T) structure (space group: P3m1)
  • Light weight, highly stable and low-cost 
  • Known to be a semimetal in when in bulk form and a semiconductor when strain or pressure is applied in the monolayer form

Applications of Titanium(IV) Sulfide

Titanium(IV) sulfide single crystals can be used to prepare monolayer and few-layer TiS2 by mechanical or liquid exfoliation. Titanium(IV) sulfide powder is suitable for liquid chemical exfoliation to prepare TiS2 nanosheets and nanoparticles down to few-layer films. 

Monolayer titanium(IV) sulfide is the lightest member of the transition metal dichalcogenide family. It has promising applications in energy conversion and storage systems. 2D titanium(IV) sulfide has also been used in supercapacitors, and ultrafast fiber laser applications.

Two-dimensional thin layer nanosheets made from chemically-exfoliated titanium(IV) sulfide powder are generally used as electrode materials in storage batteries. Atomic-layered TiSquantum dot materials prepared from liquid exfoliation of  TiS2 powder can also be used as electrocatalysts for hydrogen evolution reactions (HER).

TiS2 enables desalination of the sea water by the removal of sodium cations involving intercalation mechanism without employing an ion exchange membrane.
