Experimental Use of TiO2 Nanoparticles for Reducing Pollutant Depositions on Road

Atmospheric deposition of pollutants is a major challenge for the environmental governance and management of cities. Different depositions could be harmful especially on ground and roads. In particular, in areas were industrial activities are located and/or significant car traffics occur, depositions on roads are harmful for all people especially for pregnant women who will be attacked as well as other people. The main effects are risks of breathing pathologies and possible cancer as a long-term consequence. The main objective of this research is to illustrate the latest achievements in terms of the use of titanium dioxide to be spread on a road as a cover film to neutralize pollutants as NOx, SOx, NH3, CO, dusts and aromatic substances. The removal is performed by means of a photocatalytic reaction. The nanoparticles play a key role in this process. The paper show some experimental and interesting results.
