What Is Hydroxyl Group on The Surface of Tungsten Oxide?

Hydroxyl group on the surface of tungsten oxide.

The hydroxyl group on the surface of tungsten oxide refers to the hydroxide ion (OH-) or hydroxyl group (OH) group on the surface of the tungsten oxide material. They form chemical bonds with tungsten and oxygen atoms, attaching to the tungsten oxide surface. In tungsten oxide, hydroxyl groups can be formed by adsorbing water molecules (H2O) or directly reacting with oxygen atoms. When tungsten oxide is exposed to a humid environment, hydroxyl groups on the surface can be formed by adsorbing water molecules in the environment. In addition, tungsten oxide can also generate hydroxyl groups by reacting with water vapor or in some chemical reactions.

The hydroxyl groups on the surface of tungsten oxide play an important role in many application fields. For example, in catalytic reactions, hydroxyl groups can participate in the reaction process as active sites or intermediates. In addition, hydroxyl groups can also affect the surface properties of tungsten oxide materials, such as adsorption performance, surface charge and chemical reactivity, etc.
