| Popis: | Traditional photocatalysis is here brought forward for both the use of nanosized TiO2crystallites and the possibility to have a release of TiO2particles during the final use of the manufactured products. In the present paper both the preparation and characterization of a new generation of photocatalytic tiles are presented. The originality of these products is the surface presence of microsized TiO2as it is not clear yet the impact of the nanoparticles on both human and environmental safety. TiO2is here mixed with a silica compound and the final thermal treatment at 680°C allows the complete surface vitrification which, in turn, makes the tiles surface strongly resistant to abrasion. Photocatalytic efficiency towards the degradation ofNOxin gas phase was measured in both a batch and a plug-flow reactor. The latter reactor configuration was also modeled by digital simulations. |
