What Are The Oxygen Vacancies on The Surface of Tungsten Oxide?

Tungsten oxide (tungsten oxide) is a compound composed of tungsten and oxygen, which has many different oxidation states. In tungsten oxide, an oxygen vacancy (oxygen vacancy) refers to the absence of an oxygen atom in the crystal lattice. The formation of oxygen vacancies is usually due to the departure of oxygen atoms or defects in the structure. In tungsten oxide, when an oxygen atom leaves a lattice site, it leaves an oxygen vacancy. This may be due to increased temperature, chemical reactions, or other external factors.

Oxygen vacancies play an important role in tungsten oxide, affecting its properties and performance. They can alter the electrical, magnetic and optical properties of materials, as well as their catalytic activity. Oxygen vacancies can also affect key properties such as electrical conductivity and ion transport of tungsten oxide.

Studying and controlling the generation and behavior of oxygen vacancies in tungsten oxide materials is of great significance for understanding and optimizing their properties. It is also one of the research hotspots in many related fields such as energy storage and conversion, catalysis, electronic devices, etc.
