Preparation of defective tungsten oxide nanopowder is widely studied as defective tungsten oxide nano powder has wide applications in solar power generation, seawater desalination, and sewage treatment. Defective tungsten oxide nanopowder is a kind of photothermal conversion material, which can convert sunlight into heat energy to heat the base liquid, and realize the photothermal conversion. Specifically, the application of tungsten oxide nanoparticles is to convert water into steam on a large scale under the radiation of the sun or solar simulator to achieve solar power generation, seawater desalination, or sewage treatment. Well, do you know how to prepare defective tungsten oxide nanoparticles?

WO3 nanoparticles are often made into gas sensor for detecting various toxic gases. For example, WO3 nano particles have high sensitivity and selectivity to trimethylamine and high sensitivity to acetic acid, acetaldehyde, acetone, and ethanol gas.

WO3, an n-type semiconductor, is an excellent gas-sensing material and has good sensitivity to toxic gases such as NO2. According to the experts, in recent years, with the rapid development of economy and industry, toxic gases such as NO2 have caused serious environmental pollution problems, such as acid rain, photochemical smog, etc. Due to their toxicity and destructiveness, the detection of NO2 and other toxic gases has paid much attention.

WO3 nanopowder is n-type semiconductor that has wide applications in smart windows, gas sensors, etc., so it has been paid much attention including its preparation. Here is a preparation method of WO3 nanopowder.
