The photocatalytic activity of tungsten oxide (WO₃) refers to its ability to promote photocatalytic reactions under light conditions. Photocatalysis is a method that uses light energy to stimulate electron transfer processes on the surface of catalysts, thereby initiating chemical reactions. In the photocatalytic process, the catalyst excites electrons by absorbing light energy, and utilizes these excited state electrons to participate in redox reactions or other reactions. Photocatalysis can be used in environmental purification, water splitting, organic synthesis, photoelectric conversion and other fields. Tungsten oxide has good photocatalytic activity, especially in the visible range. When tungsten oxide is irradiated with visible light, its band structure enables it to absorb photon energy and generate electron-hole pairs. These electron-hole pairs can migrate and react on the surface of tungsten oxide, participating in redox or other catalytic reactions.
The enhancement of photocatalytic activity can be achieved through various approaches. One of the methods is to increase the active sites on the surface by adjusting the crystal structure, morphology and doping of tungsten oxide to improve the light absorption capacity and electron transport efficiency. Another approach is to enhance the photocatalytic effect by using in combination with co-catalysts or photosensitizing dyes, so that light energy can be more efficiently converted into energy for chemical reactions.
The photocatalytic activity of tungsten oxide can be applied in many fields. For example, it can be used for photocatalytic decomposition of organic pollutants, photocatalytic water splitting to generate hydrogen, photocatalytic carbon dioxide reduction to prepare combustible fuels, etc. These applications exploit the photocatalytic activity of tungsten oxide for efficient and sustainable energy conversion and environmental purification. In conclusion, the photocatalytic activity of tungsten oxide refers to its ability to promote photocatalytic reactions under light conditions. This activity is determined by the energy band structure and surface properties of tungsten oxide, which can be applied in various photocatalytic reactions and energy conversion processes.
