Tungsten oxide powder not only has photochromic properties, but also has photocatalytic properties. Therefore, it can be used in the field of window heat insulation film and photocatalytic degradation of organic pollution. However, the photocatalytic performance of tungsten trioxide needs to be further improved to make it better applied in the field of catalysis. And the method for improving the photocatalytic performance of WO3 includes elemental doping and the like. For example, S, I-doped tungsten trioxide may be prepared by…
