Titanium dioxide onto polyethylene for water decontamination

TiO2 aqueous suspensions under illumination of UV range (310-400 nm UV-A) have demonstrated a big potential for water decontamination and disinfection for human consume. Separation of TiO2 from the process is not easy. Supporting TiO2 to a proper substrate avoid the separation step after the photoca...
