Photocatalysts for Indoor Air Pollution: A Brief Review

Part of the Environmental Chemistry for a Sustainable World book series (ECSW, volume 36)


Photocatalysis is one of the fastest growing technologies for the treatment of pollutants, utilizing the mechanism of reaction with the help of light (photo emissions). Photocatalysis has captured broad academic and research interest during the past three decades for its potential of controlling pollution in air and water. Its qualities, such as low cost and high efficiency, have caused researchers all over the world to focus on it and also promoted many industrial applications and much research. Photocatalysis has been used to remove major air pollutants, disinfect water, and oxidize various organic chemicals. In this connection, this chapter considers the properties of the ideal photocatalyst, available photocatalytic materials for air pollution control, common indoor air pollutants and their severe health effects, and purification techniques for indoor air pollution. Furthermore, photocatalytic oxidation techniques for the removal of volatile organic compounds are discussed in detail.
