Yellow tungsten oxide nanopowder is also called tungsten trioxide nanopowder, which is an n-type semiconductor oxide material. As a photocatalyst, tungsten trioxide nanopowder may:
1. Photocatalytically degrade organic pollutants;
2. Catalyze the organic and inorganic synthesis;
3. Be applied for water splitting to produce hydrogen and separate out oxygen;
4. Be applied in photocatalytic reduction of metal ions, such as heavy metal chromium, mercury, lead, and so on;
5. Be used in photocatalytic degradation of organic pollutants, such as formaldehyde.
At present, there are many research achievements on WO3 photocatalyst, such as:
1. Tungsten trioxide photocatalysis water producing hydrogen. In 1976, Hodes applied WO3 to the photocatalytic water system for hydrogen production for the first time, after which people conducted extensive research on the WO3 photolysis water system.
2. Rare earth doping WO3 photocatalyst. A large number of studies have shown that doping is an effective means to improve the photocatalytic activity of WO3.
3. There are many types of composite photocatalysts such as WO3/α-Fe2O3, WO3/CeO2, WO3/Y2O3, WO3/TiO2, and WO3/CdS/W, etc.
