The doping of tungsten oxide electrocatalytic hosts refers to the doping process of introducing other elements or compounds into the structure of tungsten oxide (WO₃). This doping can change the physical and chemical properties of tungsten oxide, including its electrocatalytic activity, stability, optical properties, etc., thereby regulating its electrocatalytic performance. By introducing doping elements or compounds into the tungsten oxide structure, the following aspects of regulation can be achieved:
Catalytic Activity of Tungsten Oxide Electrocatalytic Existence Doped
Doping can adjust the chemical properties and electronic structure of the tungsten oxide surface, thereby affecting its catalytic activity. Different valence states or electronic structures of doping elements can change the characteristics of surface adsorption sites, generation of oxygen vacancies, and electron transport, etc., thereby affecting the rate and selectivity of electrocatalytic reactions.
Doping Stability of Excipients in Tungsten Oxide Electrocatalysis
Tungsten oxide may be affected by chemical corrosion or structural damage in certain catalytic reactions. By doping other elements or compounds, the chemical stability and corrosion resistance of tungsten oxide can be improved and its service life can be extended.
Photocatalytic properties of tungsten oxide electrocatalyzed by doping with hosts
Some doping elements can adjust the optical properties of tungsten oxide, making it responsive to visible light. In this way, the photocatalytic application field of tungsten oxide can be expanded, such as visible light catalyzed water splitting to produce hydrogen, etc.
The common doping of tungsten oxide electrocatalytic hosts includes tungsten dislocation, tungsten doping, transition metal doping, non-metal element doping, etc. The specific doping method and effect depend on factors such as the choice, concentration, and doping method of doping elements. It should be noted that the doping of tungsten oxide electrocatalytic hosts is a complex subject, which requires in-depth research and optimization to achieve effective regulation of electrocatalytic performance. Therefore, systematic experimental and theoretical studies are required to determine the optimal doping strategy and conditions for specific application requirements.
