Tungsten disulfide coating is a continuous solid film coated by tungsten disulfide once. It is formed by spaying or blushing film-forming agent on the friction surface. And the film-forming agent is made from tungsten disulfide powder and organic binder or inorganic binder. Tungsten disulfide coating is regarded as the most promising solid lubrication coating.

Tungsten disulfide film can be successfully prepared by the sulfurization of tungsten trioxide film, which is deposited on the substrate. As the method has attracted the attention of people, the performance of tungsten disulfide film prepared is being studied by more and more people.

Heterojunction of tungsten disulfide and tungsten trioxide monohydrate is a transverse heterojunction formed by tungsten disulfide and tungsten trioxide monohydrate with covalent bonds. It has great potential application value in the field of photocatalytic semiconductor nanocomposites.

Tungsten disulfide/titanium silicide composite catalyst has broad application prospects in water-splitting for hydrogen production. It can be prepared by raw materials of ammonium tetrathiotungstate and titanium silicide. And ultrasonic-electrodepositing method and calcination method are applied in the preparation process.
