Tungsten disulfide nanosheet is a typical transition metal sulfide. It is a black powder with a chemical formula of WS₂ and a molecular weight of 247.97. It has the characteristics of low friction coefficient, good thermochemical stability and photoelectric properties. It is widely used in lubricants, catalysts, energy storage electrode materials and other fields.

In industrial production and environmental monitoring, the rapid and accurate detection of gas components is of utmost importance. Violet tungsten oxide (WO₂.₇₂), a material with unique electrical and surface properties, is widely used in the field of gas sensing due to its excellent gas sensitivity. It provides reliable support for safety monitoring and environmental protection.

Tungsten oxide, as the core "secret weapon" of smart windows, is like a bright star in the field of materials science, shining with a unique light. Its chemical formula is WO₃-x, which is a compound formed by the close combination of tungsten and oxygen. Its appearance presents a variety of colors, the most common of which are light yellow, yellow, orange-yellow, blue and purple, as if it was given a unique color code by nature.

As environmental pollution becomes increasingly severe today, how to efficiently and environmentally friendly manage pollution has become the focus of global attention. Violet tungsten oxide (WO₂.₇₂), an emerging photocatalytic material, is emerging in the field of environmental governance with its unique advantages, acting as the "environmental guardian" that safeguards our green mountains and clear waters.
