Tungsten trioxide nanopowder may shield the near-infrared and ultraviolet (UV) rays, and thus can be used for preparing window heat insulation film. In hot summer, if the window is coated with the heat insulation film using WO3 as material, it will be cooler in your home or office.
Certainly, tungsten trioxide also has good catalytic performance, and therefore has a very broad application prospect in the field of catalysis. With the further development of material science, other properties of tungsten trioxide will also be widely used in the field of materials.
In the study of partial oxidation of methane, using WO3/SiO2 as a catalyst, formaldehyde is the major product with the exception of CO and CO2. While two carbon hydrocarbon compounds are mainly produced when K+ is used as a co-catalyst. The difference from the former is mainly that there is the formation of K2WO7 phase in the latter catalyst.
