Environmental applications of photocatalysis using TiO2 have attracted an enormous
amount of research interest over the last three decades [1-4]. It is well established that slurries
of TiO2 illuminated with UV light can degrade to the point of mineralization almost any
dissolved organic pollutant. Nevertheless, photocatalysis, particularly in aqueous media, has
still not found widespread commercial implementation for environmental remediation. The
main hurdle appears to be cost, which is high enough to prevent the displacement of existing
and competing technologies by photocatalysis.
