TiS2 is a golden yellow solid that belongs to the family of transition metal dichalcogenides. The structure consists of a layer of titanium atoms sandwiched between two layers of sulfur atoms that are covalently bonded to the titanium atoms. Like other group IV dichalcogenides, it crystallizes in an octahedral (1T) phase rather than a hexagonal (2H) one. It is the lightest member of this family and has promising applications in energy conversion and storage systems. It can be intercalated with an alkali metal to form a lithium-titanium disulfide cathode material for rechargeable batteries.
The crystal structure of titanium disulfide provides high binding capacities for transition metal ions to its sulfide ligands. Hence, it is highly electrochemically active. TiS2 is a good cathode material for rechargeable batteries and exhibits excellent electrical conductivity. This crystalline material is a semiconductor with a low band gap, and a small overlap between its conduction and valence bands.
Titanium(IV) sulfide can be produced by reacting TiCl4 with hydrogen sulfide in the presence of a metal alkoxide catalyst. The resulting solution is then annealed in vacuum to form a thin film.
Titanium(IV) sulfide is toxic by ingestion, inhalation, and skin absorption. Ingestion may cause gastrointestinal problems. This compound reacts slowly with water to generate hydrogen sulfide gas, which is toxic and flammable. Contact with water may also generate irritating, corrosive and/or toxic gases. It is very flammable and can cause serious injury or death if inhaled.
