FOTOAir Unit activities are focus on the photocatalytic treatment of gaseous pollutants. In this field, the Unit works with different real emissions. These emissions include Volatile Organic Compounds (HCHO, C2HCl3) and Inorganic Compounds (NOx, H2S).

Currently the Life-MINOX-Street project is one of the most important projects inside this research line. The TiO2 is being incorporated in building materials in order to reduce NOx pollution in an urban environment.
