Tungsten oxide nanopowder, which may he used for producing near-infrared shielding material, has a certain photocatalytic performance, however, its photocatalytic activity is not high. Therefore, it is necessary to find a method to enhance the photocatalytic activity of tungsten oxide. For example, the photocatalytic activity of tungsten oxide may be improved by the method of metal load. Four kinds of metal load tungsten trioxides were studied, including Rh/WO3, Pt/WO3, Au/WO3 and Ag/WO3. It was found that the photocatalytic activities of…
