Polluted wastewater and anti biotic wastewater are typical toxic and harmful industrial wastewater that are difficult to degrade, such as wastewater from pesticide industry and wastewater from some chemical industry. Because of the high concentration of fungicides in wastewater, which can kill and inhibit the growth of microorganisms, it is difficult to treat this kind of wastewater directly by biotechnology.

The preparation of composite of tungsten disulfide and graphene involves the four steps: the preparation of graphene oxide, the preparation of RGO, the preparation of tungsten disulfide and the preparation of composite of WS₂ and RGO. This is a simple preparation method with low cost.

Lubrication of aircraft tail is very important. With good lubricating performance and excellent resistance to high temperature and extreme pressure, tungsten disulfide has high application value in aircraft tail lubrication.

With good lubricating performance and excellent substrate adhesion, WS₂ can be applied in catadioptric telescope lubrication. The lens tube and other important parts can be lubricated with this material to ensure the high efficiency and stability of the celestial observation.
