Physical or chemical modification to change the surface properties and electronic structure of tungsten oxide surface, thereby enhancing the visible light absorption and photocatalytic activity of tungsten oxide. Surface modification can be done in various ways, the following are some common surface modification techniques:
Co-Deposition Modification Of Tungsten Oxide
Introduce other metals or compounds to the surface of tungsten oxide by co-deposition or co-precipitation with other metal ions. This co-deposition modification can change the chemical composition, crystal structure and energy band structure of the tungsten oxide surface, and improve its light absorption and photocatalytic activity. Common co-deposition methods include chemical deposition, electrodeposition, and impregnation.
Tungsten Oxide Chemical Modification
Introduce functional molecules or compounds on the surface of tungsten oxide by chemical methods, such as organic dyes, semiconductor quantum dots, etc. This chemical modification can increase the light absorption ability of the surface of tungsten oxide, change the surface electronic state and energy band structure, and improve the visible light catalytic activity.
Tungsten Oxide Surface Modifier Coating
Use surface modifiers (such as organic molecules, polymers or metal oxide nanoparticles, etc.) to cover the surface of tungsten oxide to form a composite material structure. The coating of this surface modifier can increase the light absorption capacity, reduce the electron-hole recombination and improve the photocatalytic activity of tungsten oxide.
Tungsten Oxide Nanostructure Modification
By preparing nanostructures of tungsten oxide, such as nanoparticles, nanowires, nanosheets, etc., the surface area and interface active sites can be increased, the light absorption and electron transmission efficiency can be improved, and the visible light response performance can be enhanced.
Through the above surface modification technology, new energy levels can be introduced on the surface of tungsten oxide, the crystal structure and energy band structure can be changed, and its visible light absorption ability and photocatalytic activity can be enhanced. This surface modification can improve the application performance of tungsten oxide in visible light catalytic decomposition of organic pollutants, photocatalytic water splitting hydrogen production, etc., and expand its application potential in optoelectronic devices and photovoltaic energy storage and other fields.
