Tungsten trioxide nanopowder applying for heat insulation masterbatch not only has good ding of shielding ultraviolet (UV) rays and near-infrared rays, but also has good catalytic ding. And there is no doubt that the heat insulation material using WO3 as material will have a wide application in the field of heat insulation.
Application of Tungsten Trioxide in Field of Catalysis
There are a lot of tungsten-based catalysts including tungsten, tungsten compounds, tungsten sulfides, and heteropolytungstic acids. They all have good catalytic performance for many reactions such as hydrodeoxygenation, oxidation, hydrocarbon isomerization, and alkylation, etc. And they all have a potential application in petrochemical industry. According to related studies, pure tungsten trioxide has almost no catalytic activity due to the lack of metal properties. And pure WO3 is difficult to obtain stable catalytic performance. Therefore, the pure tungsten trioxide is generally partially reduced, or doped with active components, or modified, to improve its catalytic performance.
