Titanium disulfide powder's introduction

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.

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

Applications of titanium disulfide powder

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

Monolayer titanium disulfide is the lightest member of the transition metal dichalcogenide family. It has promising applications in energy conversion and storage systems. 2D titanium disulfide has also been used in non-linear optics, supercapacitors, and ultrafast fiber laser applications.
