As a type of transparent thermal insulation nanopowder, nano tungsten oxide has the characteristics of high transparency and high shielding rate to infrared rays and ultraviolet rays. Tungsten oxide is also a photocatalyst.
Tungsten oxide can be applied in heat insulating glass, including smart glass, electrochromic glass and photochromic glass when it is used as a heat insulating material.
And tungsten oxide can be applied in photocatalytic hydrogen production when it is used as a photocatalyst. When it comes to photocatalysis, what has to be mentioned is - forbidden band width. The forbidden band width is an important indicator affecting the photocatalytic performance of semiconductors because it is directly related to the energy of light required by photogenerated carriers. The forbidden band width of tungsten oxide is not only related to the degree of distortion of the constituent component WO6, but also to other components in its crystal structure, such as structural water.
