Tungsten trioxide, as a catalytic material for hydrogen production from water decomposition, has the advantages of photoelectric double response effect, stability, low light-on voltage, high hydrogen production efficiency, and is also a good electrochromic material.

Ultra-fine cemented carbide made of ultra-fine tungsten carbide powder has high strength and high hardness, which effectively solves the contradiction between hardness and strength of traditional cemented carbide. It is widely used in the manufacture of integrated circuit board micro drill bits and dot matrix printing. The table machine prints needles, precision tools, difficult-to-machine materials, woodworking tools, medical drills, etc.

90 Sr is an important heat-releasing nuclide in fragment solution. Separation of 90 Sr from fragment acidic solution can greatly reduce the cost of subsequent treatment of radioactive waste liquor. However, the separation of 90 Sr from fragment acidic solution is a very challenging task.

Tungsten disulfide is a typical layered compound with graphene-like structure. The atoms in the layers are bound by strong covalent bonds, and the van der Waals force between layers is weak. Tungsten disulfide has special mechanical, optical and electrical properties due to its unique structure. Therefore, tungsten disulfide nanomaterials are not only widely used in lubrication and wear fields, but also in catalysis (such as visible light degradation of organic pollutants, visible light hydrogen production, electrocatalytic hydrogen production), lithium batteries (such as anode materials), photoelectric conversion (such as light emitting diodes, solar cells) and other fields. A wide range of attention has been paid by scientific researchers.
