The route for the decreasing of air pollutants using photocatalysis over titanium dioxide incorporated in to different kinds of concrete surfaces
Original language description
Elevated amount of the gaseous pollutants occurring in close vicinity of traffic arteries represent still pressing issue. One way, how to fulfill the efforts for decreasing of pollutants concentration in localities affected by the traffic is utilizing photocatalytically active titanium dioxide (TiO2) applied on the surface of concrete structures and buildings located in close area of traffic junctions and other localities influenced by traffic. The photocatalytical reactions can run only if the irradiation with suitable wavelengths interacts with surface of a photocatalyst. Final effect of degradation over photocalysts is strongly dependent on light intensity, humidity and air flow rate as well as on the concentration of gaseous pollutants. Except theconditions mentioned above, the nature of the photocatalyst, its surface structure and of course its amount on the surface of the hardened concrete plays crucial role in the photodegradation process.
