Photocatalytic porcelain gres Tiles with micro-sized TiO2: tests of degradation of dyes in water

Some particular drawbacks due to the industrial use of nano-sized TiO2 (safety, recovery) can be closed with the choice of micro-sized TiO2 in the anatase form as photocatalytic powder. Good photocatalytic performance in the degradation of three organic dyes in water phase were obtained. Furthermore, tests on industrially prepared photocatalytic tiles, having the surface of porcelain tiles hot-coated with micro-sized TiO2, were also performed. The obtained results can represent a good alternative to TiO2 suspensions and pave the way for the fully industrial use of photocatalysis in environmental remediation
