Photocatalyst are materials that induce photocatalytic reaction under photoirradiation. A general definition of photocatalysis, a conceptual name of photocatalytic reactions, is a chemical reaction induced by photoabsorption of a solid material, or “photocatalyst,” which remains unchanged during the reaction. With the promotion of Industrialization process progresses continue, more and more urban residents living in an environment with the extremely high of air pollution index. In recent years, since the striking of haze, the indoor air purification has caused more people's attention. Because of the explosive growth of air purification demanding, photocatalytic product in the market emerge in endlessly. Wherein, the most representative product is photocatalyst which leading by titanium dioxide, that is the champion with its superior performance.

 

Tungsten trioxide is the photocatalyst material which has a broader spectral response range compared to titanium dioxide, and it is responding to the visible light. Compared to the traditional titanium dioxide photocatalytic product, the environment demand of tungsten trioxide is greatly reduced; the main reason is that it can use the room light or sunlight outside, and high effect will be brought out under the faint visible light. Besides, tungsten trioxide has 30 times of decomposition of purification capacity more than the titanium dioxide, that is to say it has good decomposition reduction effect for a variety of odors, bacteria, viruses and VOC substances, moreover, it is safe with non-toxic, no secondary pollution will bring out, and known as the "air purification master. "

 

Reactive oxygen is also generated when the surface of photocatalytic particles from which electrons have already been ejected come in contact with water molecular, contributing to the efficiency of the air purifying effect. The tungsten oxide photocatalyst shows catalysis effect, however, “photocatalyst” should act catalytically, i.e., without change, under light. Although molecules or metal complexes dissolved in solution or in the gas phase, not solid materials, can drive such photoinduced reactions without change during the reactions, they are called “photosensitizer” but not “photocatalyst.” photoinduced reactions are, in principle, initiated by photoabsorption,

 

Photocatalyst which is taking tungsten oxide as the raw material can form tungsten and sodium ions under the faint light indoor, also form the electrons and holes by absorbing light, thus to release hydroxyl radicals and reactive oxygen species, and finally decompose indoor viruses, bacteria, VOC and remove odor. Under the irradiation of the effective light, the surface of tungsten oxide will have an oxidation-reduction reaction, the oxidizing power is generally several times of bleach, which can be widely used in construction, kitchen supplies, medical equipment, air filters and clean kitchen supplies and so on.

 

The moment you turn on the light or let the sunlight into your room, the clean and better life has already begun, the air purification master - tungsten trioxide photocatalyst will really bring you a clean, fresh room environment.
