Researchers have prepared a new structural yellow tungsten oxide photocatalytic material by hydrothermal method in a high-pressure reactor. Wherein, the obtained yellow tungsten oxide (WO3) has characteristics of large specific surface area, a size in the micro-nano range, good structural stability, and a narrow band gap. So, it is convenient for applications of photocatalytic degradation of organic dyes. Moreover, preparation of yellow tungsten oxide by hydrothermal method has advantages of easy availability of raw materials, mild conditions and simple operation.…
