What is the application prospects of nano tungsten oxide WO3 powder

April 19,2021.
Nano tungsten trioxide WO3 has a large comparison area and significant surface effect. It is a good catalyst. It can be used as a main catalyst or an auxiliary catalyst, and has a high selectivity to the reaction.

WO3 has a strong ability to absorb electromagnetic waves and can be used as an excellent solar energy absorbing material and recessive material.

WO3 is an n-type semiconductor material with excellent gas sensitivity, so it can be used to make gas sensors and gas color devices.
1) In terms of environmental testing. It is used for flammable gas leakage alarm and humidity sensor. The measured gas mainly includes CO, CH4, NOX, SO2, NH3, H2, etc.
2) For civilian use. It can detect the leakage of civil gas such as natural gas, liquefied petroleum gas and city gas, as well as some unpleasant gases in public places such as houses and buildings.
3) Industry. Used to detect carbon dioxide, nitrogen oxides, sulfur oxides and other highly toxic gases in the petrochemical industry; detect hydrogen generated during the deterioration of power transformer oil; detect the freshness of perishable food such as meat; detect ethanol gas in the driver's breath concentration.
In recent years, through the joint efforts of many researchers, different degrees of progress have been made in improving the gas sensitivity and selectivity of WO3-based gas-sensitive materials, lowering the operating temperature, and performing different doping and improving processes.

The band gap energy of tungsten trioxide is about 2.5eV, and it has potential photocatalytic ability in visible light with a wavelength of <500nm. Photocatalytic degradation of organic matter is a new technology that uses sunlight to degrade organic matter, saving energy and not polluting the environment. Therefore, WO3 has potential application prospects in the treatment of water contaminated by organic dyes.
