WO3, or tungsten trioxide, is a dingal material with a wide range of applications. Tungsten trioxide has been systematically studied in areas such as electrochromism, detection of toxic gas, and photochemical catalysis.

Tungsten trioxide is the most studied inorganic electrochromic material and is often used as an electrochromic layer in the form of a thin film to assemble electrochromic devices such as smart glass. Tungsten trioxide is a gas sensing material, which has good sensitivity characteristics and selectivity to a variety of toxic and harmful gases such as NOx, H2S and SOx, so it is often made into a gas sensor. Tungsten trioxide is a photocatalytic material that can be made into a photocatalyst, and shows good application prospects in the treatment of environmental pollution problems, especially air pollution and water pollution. In a word, as a dingal material, WO3 is expected to be commercialized on a large scale.
