It is reported that porous yellow tungsten oxide, or porous tungsten trioxide (WO3), is an ideal photocatalytic material as the pore structure has a strong ability to degrade dyes. Therefore, tungsten trioxide with pore structure can be used to photodegrade dyes in industrial wastewater.

Researchers proposed a preparation method of TiO2-WO3 photocatalyst. The obtained TiO2-WO3 photocatalyst has strong visible light absorption at 400-800 nm, and has good efficiency for photocatalytic degradation of gas-phase toluene.

Studies have shown that yellow tungsten oxide, or tungsten trioxide (WO3), can be used as a catalyst to prepare a new type of air purification composite coating – an environmentally friendly functional coating.

How to prepare yellow tungsten oxide photocatalytic material? The researchers successfully prepared hexagonal WO3 photocatalytic materials by a simple hydrothermal method.
