Some particular drawbacks due to the industrial use of nano-sized TiO2 (safety, recovery) in photocatalytic processes for water remediation can be avoided choosing micro-sized TiO2. Tests on both micro-sized TiO2 powder and industrially prepared photocatalytic tiles, having the surface of porcelaingres 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 TiO2 suspensions and pave the way for the fully industrial use of photocatalysis in environmental remediation. (C) 2014 Elsevier B.V.
