Yellow tungsten oxide as a photocatalytic material can be used to produce hydrogen by photolysis of water. According to the experts, the photocatalytic material used for hydrogen production from photolysis of water should have good light corrosion resistance, electrolyte corrosion resistance, as well as a suitable forbidden band width.

Wherein, the forbidden band width is one of the decisive factors that affect the performance of the photocatalytic material. When the forbidden band width is too large, it can only absorb about 5% of the ultraviolet light in sunlight, but cannot respond to visible light, so the utilization rate of sunlight is low. While yellow tungsten oxide can meet the above requirements well. Therefore, it has a very important application prospect in the field of using sunlight to produce hydrogen by photolysis of water. Well, do you know who was the first person to use WO3 in the system of photolysis of water to produce hydrogen? – Hodes, etc.
