Tungsten oxide may be applied as a heat insulation coating for the production of products such as heat-insulating films that require high heat insulation and high transparency. Tungsten oxide powder is also a photocatalyst, which is expected to be used to treat harmful substances such as azo dyes, anthraquinone dyes and triarylmethane dyes. These dyes have relatively stable physicochemical properties, which are difficult to degrade in nature. What worse, they are difficult to be handled during processing.
At present, photocatalytic technology has attracted the attention of researchers because of its mild reaction conditions. And there is no need for secondary treatment. What is more, it may be used to handle lower concentrations of pollutants, and a more thorough process is available. Besides, research on the use of photocatalytic technology to control dyes is very mature, and many reports are reported in this area every year.
However, this technology is still difficult to apply to large-scale applications. It is mainly because other substances have a certain hindrance to the photocatalytic process in the complex sewage system. In addition, the catalytic activity of the tungsten oxide photocatalytic material needs to be further improved to better suit the practical application.
