Abstract
tSome particular drawbacks due to the industrial use of nano-sized TiO2(safety, recovery) in photo-catalytic processes for water remediation can be avoided choosing micro-sized TiO2. Tests on bothmicro-sized TiO2powder and industrially prepared photocatalytic tiles, having the surface of porcelain-grès tiles hot-coated with the same photocatalyst, were performed. Good photocatalytic performance inthe degradation of three organic dyes (rhodamine B, crystal violet and methylene blue) in water phasewere achieved. Photocatalytic tiles can really represent a good alternative to TiO2suspensions and pavethe way for the fully industrial use of photocatalysis in environmental remediationPubblicazioni consigliate
