Nano tungsten oxide may be used for the preparation of nano-ceramic color master. Tungsten oxide also has photocatalytic properties so that it can be used for photocatalytic degradation of organic contaminants, such as organic dyes, more specifically, photocatalytic degradation of triarylmethane.
Triarylmethane has been widely used in printing and dyeing, optical reagents, nonlinear optical materials and other fields. However, some triarylmethane dyes have certain toxicity, which is manifested as carcinogenic, toxic to aquatic organisms and irritating to the eyes. Rhodamine B is one of the representatives, which is mainly used in the printing and dyeing industry. In addition, Rhodamine B is a commonly used as a type of analytical reagent in the field of environmental protection, medicine and steel. However, this substance is carcinogenic, and therefore it is removed from the list of food additives. Besides, studies have shown that it can be absorbed through the skin and can be distributed to various organs with blood, causing cell necrosis. In view of this, it is necessary to treat such organic pollutants, while tungsten oxide, as a photocatalyst, can play an important role in the degradation process of organic pollutants.
