Nano Yellow Tungsten Oxide Photocatalytic Material

Nano yellow tungsten oxide, namely nano tungsten trioxide or nano WO3, is an extremely attractive semiconductor photocatalytic material that has broad application prospects in environmental pollution purification and energy regeneration. Compared with the commonly used photocatalytic materials such as titanium dioxide (TiO2) and zinc oxide (ZnO), tungsten trioxide has a smaller band gap and a larger light absorption range, which can use visible light more effectively. Wherein, visible light accounts for nearly 50% of solar radiation energy.

In addition, the volume effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nano yellow tungsten oxide are significant. Moreover, the preparation process of WO3 is simple. However, what should be noted is that, it is difficult to obtain stable photocatalytic performance of pure tungsten trioxide due to defects such as easy photocorrosion and low utilization rate of visible light. Therefore, research on how to improve the photocatalytic degradation performance of yellow tungsten oxide has important significance.
