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.

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 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.

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.

Composite of tungsten disulfide and titanium silicide has broad application prospects in water-splitting for hydrogen production as a new type of photocatalyst. It can be successfully prepared by modifying titanium silicide with tungsten disulfide.

Copper/tungsten disulfide/graphite composite electric brush can be prepared by hot-pressing sintering of electrolytic copper powder, tungsten disulfide powder and graphite powder. It is an ideal brush material with good conductivity and excellent friction performance.

Tungsten disulfide transistor is made by stripping monolayer tungsten disulfide from tungsten disulfide. And electron beam lithography is applied in the making process. WS₂ transistor with good optoelectronic performance can be used in the optoelectronic devices.

Nanomaterials refer to materials whose dimensions reach the nanometer scale in a certain dimension, two-dimensional or three-dimensional direction. It can be divided into zero-dimensional materials, one-dimensional materials, two-dimensional materials, three-dimensional materials. When a conventional material reaches the nanometer scale, its properties will be very different from usual. When the nanomaterial is a single atomic thickness, it is a two-dimensional material, representative of which is the first published graphene in 2004. In recent years, transition metal two-dimensional materials have also received great attention from scientists, such as tungsten disulfide, molybdenum disulfide or tungsten diselide, which have great potential for the next generation of electronic products.

Waste gases from tungsten disulfide are toxic hydrogen sulfide and some other gases. Among them, hydrogen sulfide poses a serious threat to the human health and environment. Therefore, we have to recycle the waste gases from tungsten disulfide.

To avoid resource wasting and environmental pollution, we need to emphasize the recovery of waste liquor from tungsten disulfide. It contains a certain amount of recyclable tungsten oxide and sodium sulfate.
