6.2.2 Short description
Many European cities are facing serious problems with air quality and smog. To meet the requirements by the current European legislation new technologies have to be developed. Great hope is placed on nanoparticulate catalysts to degrade the ambient air pollutants (indoor and outdoor). Target compounds include: particulate matter, NOx, soot, ozone, CO and VOCs.
