In the electrocatalytic process of tungsten oxide (WO₃), the active site refers to the specific position or structure that plays a key role in the catalytic reaction. These active sites are capable of adsorbing reactants, facilitating electron transport, and modulating reaction pathways, thereby affecting catalytic activity and selectivity. The specific description and understanding of the electrocatalytic active sites of tungsten oxide are still under study, and no completely clear conclusions have been obtained. However, the following are some widely studied and recognized electrocatalytic active sites in tungsten oxide:
Oxygen vacancies on the surface of tungsten oxide
Oxygen vacancies on the surface of tungsten oxide are a common candidate for active sites. They provide sites for reactant adsorption and reactive centers, and also participate in the electron transport process.
Hydroxyl on the surface of tungsten oxide
The hydroxyl group (OH) on the surface of tungsten oxide is also considered as one of the active sites. The hydroxyl group can adsorb the reactant and promote the catalytic reaction.
Tungsten Oxide Electrocatalytically Active Defect Sites
Defect sites in tungsten oxide crystals, such as oxygen vacancies, tungsten dislocations, etc., may also serve as active sites. These defect sites have the ability to regulate reactant adsorption and electron transport, which play an important role in the electrocatalytic activity. The specific nature and relative importance of the electrocatalytically active sites in tungsten oxide depend on the type of catalytic reaction, the conditions, and the characteristics of the tungsten oxide sample studied. Different electrocatalytic reactions may involve different active sites, so for different reactions, there may be different active site mechanisms. Therefore, more in-depth research still requires further characterization and understanding of tungsten oxide under different reaction conditions.
