Nano-Tungsten Oxide Properties and Application

Tungsten oxide (WOx) is a widely used transition metal oxides, tungsten oxide research people can be traced back to the 17th century, when some people study the properties of LiWO3, WO3 and synthetic NaWO3 and other content. With the development of nanotechnology, the preparation and analysis of tungsten oxide nanostructures are also more and more attention. Tungsten oxide nanostructures can significantly improve the performance of this important functional material, and given relative to the non-state in terms of the unique properties of nano, including:

(1) Increaseing the area / volume ratio, thereby providing more surface area for physical and chemical reactions; (2) significantly change the surface energy of the tungsten oxide, thereby changing the structure of the material surface bonded to different atoms;

(3) Quantum confinement effect, inherent nanostructured materials can significantly affect small charge transfer bandwidth and optical properties.

Tungsten oxide nanostructures with special versatility and unique properties, in many areas of condensed matter physics, solid state chemistry, where is a versatile metal oxides are studied in depth. Electrochromic applications, compared to TiO2, ZnO, NiO, etc., more in-depth study of tungsten oxide; in photocatalysis and sensors, tungsten oxide nanostructures is also of concern; research in solar cells, nano tungsten oxide Full oxidized form, tungsten oxide, although not as extensive as TiO2 and ZnO by in-depth research, but due to have similar features, but also cause for great concern. In recent years, some people will nanostructured tungsten oxide material supercapacitor electrode material for research, access to high performance super capacitor.

China has a very rich tungsten ore reserves, the development of high performance tungsten oxide material, with considerable significance.
