In daily life and industrial production, the operation of mechanical equipment relies on the support of lubricating materials. Lubricating materials play a crucial role as they can reduce friction and wear between mechanical components, lower energy consumption, and extend the service life of equipment. In recent years, tungsten disulfide nanosheet (WS₂ nanosheet), as a new type of lubricating material, has gradually become a "star material" in the lubrication field, thanks to its unique structure and excellent properties.

In the world of nanomaterials, the tungsten disulfide nanosheet (WS₂ nanosheet) is gradually becoming a focal point of scientific research. This material is widely used in the energy field due to its unique physical and chemical properties. As global demand for sustainable energy continues to grow, the WS₂ nanosheet offers new possibilities for addressing energy challenges.

Tungsten disulfide nanosheet (WS₂ nanosheet) consists of tungsten and sulfur. Its structure resembles a sandwich, with one or more layers of tungsten atoms sandwiched between two layers of sulfur atoms, and these layers are held together by weak van der Waals forces. This unique layered structure endows the WS₂ nanosheet with many excellent physical and chemical properties, making it highly effective in the lcatalysis field.

Yellow tungsten oxide (WO₃), as a novel and highly efficient catalyst, demonstrates remarkable potential in various industrial catalysis fields due to its unique physicochemical properties. It not only possesses excellent photoelectric properties but also plays a crucial role in key areas such as environmental governance and energy conversion, offering new possibilities for the development of the green chemical industry.
