Yellow tungsten oxide for air purification is an emerging photocatalyst product, which is different from the air purification products with common adsorption and filtration methods on the market. Compared with traditional photocatalyst products, the requirements of tungsten trioxide on the use environment are greatly reduced. It can exert high effects under weak visible light such as indoor lights or sunlight, so it has been widely used in homes, companies, schools, hospitals and other places.

Research shows that under weak visible light indoors, compared with the previous titanium dioxide photocatalyst products, yellow tungsten oxide photocatalyst has more than 30 times its decomposition and purification ability. For a variety of odors, bacteria, viruses and VOC substances, tungsten oxide photocatalyst has a good decomposition and reduction effect. In addition, it is safe, non-toxic, and does not produce secondary pollution (The chemical spray may have secondary pollution.). So, yellow tungsten oxide photocatalyst may replace titanium dioxide photocatalyst for air purification.
