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.

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.

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.

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.
