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.

Researchers have prepared a new structural yellow tungsten oxide photocatalytic material by hydrothermal method in a high-pressure reactor. Wherein, the obtained yellow tungsten oxide (WO3) has characteristics of large specific surface area, a size in the micro-nano range, good structural stability, and a narrow band gap. So, it is convenient for applications of photocatalytic degradation of organic dyes. Moreover, preparation of yellow tungsten oxide by hydrothermal method has advantages of easy availability of raw materials, mild conditions and simple operation.

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

Defective yellow tungsten oxide nanoparticle can be used to convert solar energy into thermal energy, thereby developing a new type of photothermal conversion material.
