Abstract

Photocatalitically Active Concrete: How Innovative Construction Materials Can Contribute to the Degradation of Dangerous Air Pollutants. The handling of environmental pollution caused by air pollutants like NOX, SO3 and volatile organic compounds (VOCs) is still a major challenge, especially in urban areas. One possibility to degrade these substances is by their oxidation on the surface of an illuminated photocatalyst, like the well known white pigment titanium dioxide (TiO2). Under illumination, oxidizing species are formed on the TiO2 surface, which are then able to decompose organic and inorganic species. By direct adding of or supplementary coating with the photocatalyst innovative building materials like concrete, plaster, floor plates and roof tiles are accessible, which not only fulfill their main task but also improve the air quality of the environment.
