Tungsten Oxide nanoparticles Used in Photocatalysis

Air purification: as the catalyst at room temperature with nano tungsten oxide, can use oxygen in the air and water vapor and other pollutants are oxidized and thus to make the air cleaner, etc., such as sulfides, nitrides, organic matter and other harmful gases . In addition, also widely used for industrial waste gas generated by the photocatalytic degradation.

Fogging and self-cleaning: the nano-plated tungsten oxide thin film on a substrate, compared with tungsten oxide nano-powders, because of its relatively large surface area, and thus the hydrophilic performance is very good, when a large amount of water vapor or liquid drops in the formation of a uniform film of water on top of the tungsten oxide film, when the strong ultraviolet light shines nano tungsten oxide film will make a strong oxidizing ability, so you can put a lot of organic matter decomposition is no absorption above the contaminated water and carbon dioxide.

Antibacterial: tungsten oxide nanoparticles in the photocatalytic process can produce a large number of optoelectronic and photogenerated holes, optoelectronics and photogenerated holes can be generated using the above water adsorbed on the catalyst surface is formed by oxidizing light group and an oxygen dianion, which may be due to bacterial cells or bacterial components of the reaction, can completely kill bacteria, while a large number of bacteria released by the toxic compound can be generated photoelectron photogenerated holes and degradation, which can effectively prevent the virus again pollution caused by the release of toxic pollutants we found smaller the particle size of the tungsten oxide nanoparticles from a large number of experiments, because of its larger surface area and therefore have a good effect, while the photocatalytic nano tungsten oxide sterilization effect, in it ends the light irradiation period of time but also have the ability to sterilization.
