In the present work the degradation of NOx compounds employing concrete paving stones provided with Ti02 to be applied in road construction is studied. The experiments were carried out in a photoreactor designed according to the standard ISO 22197-1 (2007) to assess these kind of photocatalytic materials. A kinetic model is proposed to describe the photocatalytic reaction of NO and N02 and the influence of several parameters that can affect the performance of these stones.
