What Are Oxygen Vacancies On The Surface of Tungsten Oxide?

Tungsten oxide is an oxide compound whose chemical formula can be expressed as WOx, where x represents the amount of oxygen. Oxygen vacancy refers to a vacancy or defect in an oxide due to the absence of oxygen atoms.

In tungsten oxide, oxygen vacancy refers to the absence of oxygen atoms that should be present in some positions in the oxide, resulting in the formation of a vacancy in the structure. This missing oxygen atom leads to an incomplete crystal structure and can have an impact on the physical and chemical properties of the material. Oxygen vacancies are of great significance in tungsten oxide because they can affect the electrical conductivity, optical properties, catalytic performance, etc. of tungsten oxide. In some cases, oxygen vacancies can provide additional active sites and increase the catalytic activity of materials. In addition, oxygen vacancies can also affect the electron transport and charge balance of materials, thereby affecting the electrical properties.
