Application


  • Tuning the Photo-Luminescence Properties of WO(3) Layers by the Adjustment of Layer Formation Conditions.: This research explores the photo-luminescence properties of tungsten(VI) oxide (WO3) layers and how they can be adjusted by varying the layer formation conditions. Such tuning of properties can have significant applications in energy storage and battery materials due to the enhanced electrochemical properties that can be achieved (Petruleviciene et al., 2020).

  • Decomposition of Formic Acid Using Tungsten(VI) Oxide Supported AgPd Nanoparticles.: This study investigates the catalytic properties of tungsten(VI) oxide (WO3) supported silver-palladium (AgPd) nanoparticles in the decomposition of formic acid. The findings highlight the potential industrial applications of WO3 in chemical reactions and energy storage systems (Akbayrak, 2019).


General description

Tungsten(VI) oxide, also known as tungsten trioxide, is a chemical compound with the formula WO3. Our material is a yellow crystalline solid. It is a versatile material with applications in electrochromic devices, sensors, photocatalysis, energy storage, and various other fields in material science. WO3 is used in gas and humidity sensors due to its sensitivity to various gases. It is also used as a starting material for the synthesis of tungstates, which have applications in x-ray screen phosphors and mineral separation.
