Effect of Tungsten Trioxide on Photocatalytic Degradation of Pollutants

Tungsten trioxide is a transitional product in the smelting process of tungsten production. It is yellow powder and insoluble in water and is generally used in the manufacture of high melting point alloys and cemented carbides, which can also be widely used as a raw material of reverse preparation of tungsten.

Photocatalytic technology is a method of using solar energy without pollution, and can effectively remove highly toxic and low concentration and pollutants that is difficult to deal with, which is considered to be the most effective way to control the pollution of the environment.

With the continuous development of the environmental protection industry, photocatalytic degradation as a use of radiation, photocatalyst in the reaction system of free radicals through the combination of free radicals and organic pollutants and other processes, making the pollutants were degraded to inorganic, And has pollution-free removal of pollutants technology, and now has been gradually applied to a variety of pollutant removal. As one of the earliest studied photocatalysts, tungsten trioxide is a photocatalyst in the process of degradation of pollutants because of its special structure .It has a very broad application prospects in the pollutant removal area  of chemical batteries and other fields.
