Tungsten Oxide Powder Applied for Heat Insulating Window Glass

Tungsten oxide powder, which may be used for preparing heat insulating window glass in the field of buildings and vehicles, is not only a type of photochromic material (heat insulation material), but also a kind of semiconductor photocatalyst. Tungsten oxide has good shielding rate to UV rays and infrared rays with high visible light transmittance, which means it has high heat insulation rate and high transparency. However, the photocatalytic activity of tungsten trioxide needs to be improved. Therefore, it is necessary to study on methods for improving the photocatalytic activity of WO3, for example, by compounding by semiconductor.tungsten oxide powder applied for heat insulating window glass picture
As you may have known, the essential way to improve the photocatalytic activity of materials is by increasing the separation of photogenerated electron-electron hole. For most semiconductor photocatalysts, there is inevitably a high recombination rate on photogenerated electron-electron hole. While combining a semiconductor with another semiconductor that matches its energy band can significantly improve the separation efficiency of photogenerated carriers.
