High-purity ultrafine grain size violet tungsten oxide may shield light waves from the near-infrared light. In other words, it may insulate heat intelligently. Also, violet tungsten oxide may be used as drug carrier to treat cancer in the field of biomedicine. Besides, it may be applied in photocatalytic degradation of organic pollutants to clean up environment.
Monoclinic violet tungsten oxide has the largest degree of oxygen vacancy. Compared with yellow tungsten oxide and blue tungsten oxide, violet tungsten oxide has special surface structure with highest chemical activity. Therefore, it is suitable for the production of ultrafine tungsten powder and various types of tungsten compounds with nano grain size.
In addition, metal oxide semiconductor materials have a variety of excellent properties and play a very important role in human life. In recent years, it has become a research hotspot that how to reduce the production cost of semiconductor materials and increase the energy conversion rate. As a semiconductor material, tungsten oxide has an extremely wide range of applications in photoelectrochemistry, among which violet tungsten oxide has attracted special attention due to its unique properties and structure.
