Infrared Ultraviolet Shielding Material: Tungsten Oxide Powder

Tungsten oxide powder is not only an infrared ultraviolet shielding material, but also may be used as a photocatalyst. And the hydrogen production performance of the composite photocatalyst of tungsten trioxide is higher than the photocatalytic hydrogen production activity of tungsten trioxide prepared by the same method and condition, its composite component and the sample of simple mixing of the two components.infrared ultraviolet shielding material tungsten oxide powder picture
Some researchers have synthesized the tungsten trioxide/graphene composite photocatalyst by ultrasonic method and studied the performance of photocatalytic oxygen production. It is confirmed that the hydrogen production performance of the tungsten trioxide composite photocatalyst is indeed higher than the photocatalytic hydrogen production activity of the prepared tungsten trioxide, graphene, and the simple mixed sample of the two components under the same conditions, including preparing method. The researchers also found that the chemical bond between the tungsten trioxide/graphene reduces the interfacial defects of the composite product, thereby reducing the recombination probability of photogenerated carriers. In addition, graphene can increase the light absorption range and improve light utilization.
