Tungsten Oxide Photocatalyst

Tungsten Oxide Photocatalyst

Photocatalytic also called photocatalyst, it is a kind of light irradiation, it can not afford to change itself, and it can promote chemical reactions, photocatalyst is naturally energy by converted into chemical to act as a catalyst, so that oxygen and water molecules around can excite into highly oxidizing power of the free ions. It can decomposable harmful organic substances and some inorganic substances, not only accelerate the reaction, also cause waste of resources and the formation of additional pollution.

Tungsten Trioxide Photocatalyst Applications
1: Air purification. Tungsten trioxide photocatalyst can use water vapor and oxygen in the air to remove contaminants from the air in the greenhouse, such as nitrogen oxides, sulfur compounds, formaldehyde and other harmful gases. In addition, it can also be used for photocatalytic degradation of industrial waste gas.
2: Anti-fog and self-cleaning. The use of tungsten trioxide to prepare tungsten trioxide thin films has the same photocatalytic action. The respect to the terms of the tungsten trioxide powder has high hydrophilic. Under ultraviolet light strong oxidizing, the power can be generated by the decomposition of organic matter adsorbed on the above-fog and hydrated carbon dioxide that reaches self-cleaning effect.
3: Anti-bacterial. The use of tungsten trioxide photocatalytic photo-generated electrons and photogenerated holes H₂O that adsorbed to the catalyst surface is to form an active superoxide ion with strong oxidizing, and bacterial cells or components of biochemical reactions within the bacteria, we can completely kill the bacteria, the degradation by bacteria also release toxic compounds, which prevents secondary pollution caused by endotoxin.
