Tiles functionalized with titanium dioxide (TiO2) for the elimination of air pollutants were prepared by the dip-coating process with titanium alkoxide solution. The synthesis of the coating solution consist of a chemical method employing polyethylene glycol (PEG) to obtain better dispersion and adhesion of TiO2 particles onto the ceramic substrates. Nitrogen oxides (NOx), hazardous air pollutants, were found to be efficiently removed by the thin film of photocatalyst. The effectiveness of tiles, functionalized with TiO2 thin films, has been studied in the degradation of NOx at very low concentration in continuous flow reactors.

Nitrogen oxides (NOx), hazardous air pollutants, were found to be efficiently removed by the thin film of photocatalyst. The effectiveness of tiles, functionalized with TiO2 thin films, has been studied in the degradation of NOx at very low concentration in continuous flow reactors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
