It is reported that some experts have prepared yellow tungsten oxide nanofibers (WO3 nanofibers) via electrostatic spinning with an average diameter of about 200nm. Wherein, WO3 nanofibers consist of a large amount of tungsten trioxide nano particles. These experts also studied the gas sensitivity characteristics of WO3 nanofibers-based gas sensors to H2S.

Yellow tungsten oxide, which is also known as tungsten trioxide or WO3, is an n-type semiconductor material with excellent performance and wide use. For example, yellow tungsten oxide can be used as a photocatalyst that has broad application prospects in photolysis of water and degradation of organic and inorganic pollutants in the atmosphere and water.

Yellow tungsten oxide cellulose nanocrystal composite film is a film of tungsten trioxide with a certain amount of cellulose nanocrystal that has the characteristics of good electrochromic performance, high transmission modulation and very good cycling stability for applications in electrochromic device. In a report, some researchers prepared the composite films of yellow tungsten oxide and cellulose nanocrystals via a sol-gel method and investigated their electrochromic properties.

Yellow tungsten oxide, which is also called tungsten trioxide or WO3, is developed as a photoanode to produce photoelectrochemical cell for solar energy conversion.
