Abstract
Abstract Some particular drawbacks due to the industrial use of nano-sized TiO 2 (safety, recovery) in photocatalytic processes for water remediation can be avoided choosing micro-sized TiO 2 . Tests on both micro-sized TiO 2 powder and industrially prepared photocatalytic tiles, having the surface of porcelain-gres tiles hot-coated with the same photocatalyst, were performed. Good photocatalytic performance in the degradation of three organic dyes (rhodamine B, crystal violet and methylene blue) in water phase were achieved. Photocatalytic tiles can really represent a good alternative to TiO 2 suspensions and pave the way for the fully industrial use of photocatalysis in environmental remediation.
