Introduction to Photocatalysts
Photocatalysts are substances that can accelerate chemical reactions under the action of light. This phenomenon is known as photocatalysis. When photons with sufficient energy are absorbed by the photocatalyst, electrons are excited from the valence band to the conduction band, leaving holes in the valence band. These electron - hole pairs can participate in redox reactions on the surface of the photocatalyst, enabling various chemical transformations.
Photocatalysts have a wide range of applications. In environmental protection, they can be used for air purification, decomposing harmful pollutants such as volatile organic compounds (VOCs), nitrogen oxides (NOₓ), and sulfur oxides (SOₓ). They are also employed in water treatment to degrade organic contaminants and kill bacteria. In the field of energy, photocatalysts play a crucial role in photocatalytic water splitting to produce hydrogen, which is a clean and sustainable energy source. Additionally, they are used in self - cleaning materials, where they can break down dirt and organic matter on the surface under sunlight.
