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…
