Nano tungsten oxide may be applied for preparing thermal insulation dispersion liquid, and thus be applied in heat insulating films, glasses, and plates, etc. Tungsten oxide is mainly applied in buildings or vehicles for high heat insulation. Certainly, tungsten oxide has a wider range of applications, such as photochromic films, electrochromic films, photoelectrochemical cells, gas-sensitive materials, and lithium-ion materials, etc. However, tungsten oxide has some drawbacks in photocatalysis. Therefore, tungsten oxide needs to be modified to improve its photocatalytic performance.…

Nano tungsten oxide is not only a member of the big family of near infrared shielding material, but a member of the small family of photocatalyst. As you may have known, tungsten oxide is considered to be one of the most promising photocatalysts due to its wide range of raw materials, relative low price, non-pollution and light stability. While what should be noted is that tungsten oxide photocatalyst has been successfully applied in experiments to remove water and atmospheric pollutants.…

As a type of infrared thermal insulation nano material, nano tungsten oxide has excellent heat insulation effect, which can reduce energy consumption and therefore save cooling fee on air-conditioning in hot summer. Certainly, it also improves human comfort by reduce glare effectively. Tungsten oxide is also an extremely important member of photocatalysts, which has a wide range of sources, environmental friendliness, and relatively low cost. Thus, there is no doubt that related studies on the photocatalytic performance of tungsten oxide…

As a type of transparent thermal insulation nanopowder, nano tungsten oxide has the characteristics of high transparency and high shielding rate to infrared rays and ultraviolet rays. Tungsten oxide is also a photocatalyst. Tungsten oxide can be applied in heat insulating glass, including smart glass, electrochromic glass and photochromic glass when it is used as a heat insulating material. And tungsten oxide can be applied in photocatalytic hydrogen production when it is used as a photocatalyst. When it comes to…

Nano tungsten oxide is not only a kind of infrared ultraviolet shielding material, but also a very important member of photocatalysts. Tungsten oxide exhibits very good photocatalytic activity, which is similar to the most classic photocatalyst – titanium dioxide (Ti4+). So, what is a photocatalyst? Photocatalyst refers to a general term for a chemical substance that can act as a catalyst under the excitation of photons. Titanium dioxide, particularly in the anatase form, exhibits photocatalytic activity under ultraviolet (UV) irradiation.…

As a type of transparent thermal insulation material, nano tungsten oxide has the advantages of high heat insulation (infrared shielding rate of 60-99%, varying with the addition ratio) and high visible light transmittance (visible light transmittance of 50-80%). Tungsten oxide itself also has unique physical and chemical properties, such as high temperature resistance, high stability in the air, and so on. For example, tungsten trioxide will exhibit different crystal structures at different temperatures, and different crystal structures have different physical…

Tungsten oxide powder is a type of infrared thermal insulation nano material that can be applied to smart glass in the form of thermal insulation film with high visible light transmittance and high thermal insulation. Tungsten oxide is also a catalyst that can be used in photocatalytic degradation of organic pollutants. Certainly, tungsten oxide has many other applications. Why do scientists study the photocatalytic degradation of organic pollutants of tungsten trioxide? Researchers have found that photocatalytic oxidation reactions driven by…

Tungsten oxide powder is a transparent thermal insulation nanopowder, which can be used in building glass to make “warm in winter and cool in summer” not a dream. And it is also energy-saving and environmentally friendly. Tungsten oxide is also a photocatalyst that can be used in photocatalytic hydrogen production, which means that the application range of tungsten oxide has been expanded. In order to verify the photocatalytic hydrogen production performance of tungsten trioxide, researchers have applied a photochemical battery…

Tungsten oxide powder is not only an infrared ultraviolet shielding material, but also may be used as a photocatalyst. And the hydrogen production performance of the composite photocatalyst of tungsten trioxide is higher than the photocatalytic hydrogen production activity of tungsten trioxide prepared by the same method and condition, its composite component and the sample of simple mixing of the two components. Some researchers have synthesized the tungsten trioxide/graphene composite photocatalyst by ultrasonic method and studied the performance of photocatalytic…

Tungsten oxide powder is not only a transparent thermal insulation material, but a photocatalyst, which has good visible light absorption capability with a band gap of about 2.7eV. Generally, it is considered that the suitable photocatalyst has a band gap of 1.8eV. In the study of the photocatalytic properties of tungsten trioxide, a more important research is using tungsten trioxide for photodecomposition of water to produce hydrogen. The conduction band and valence band positions of tungsten trioxide are around 0.7eV…
