Tungsten oxide nanopowder, which may be applied for the production of thermal insulation film with high heat insulation rate (mainly shielding UV and infrared rays) and high transmittance of visible light, is a type of photocatalyst with certain photocatalytic activity, while its photocatalytic performance is not so good. Therefore, some researchers have conducted a lot of researches for improving the photocatalytic activity of tungsten oxide. And they finally found that the photocatalytic activity of tungsten oxide can be enhanced by…
