Full scale demonstration of air-purifying pavement

▸ The results of a demonstration project for photocatalytic pavement are shown. ▸ The photocatalytic performance was studied in a street as well as on lab scale. ▸ The outdoor monitoring was performed in different seasons and weather conditions. ▸ The NOx concentration was in average 19% lowered by the photocatalytic street. ▸ Under ideal weather conditions the NOx reduction reached up to 45%.
