dc.description.abstractPhotocatalytic properties of anatase and other TiO2 polymorphs are widely researched and applied in practical application. In current study TiO2 films on the plasma pre-treated expanded polystyrene (EPS) foam were deposited using magnetron sputtering technique. Main properties of the films were characterised using combination of XRD, XPS and SEM techniques. Photocatalytic properties of the observed crystalline anatase phase were tested by investigating bleaching of the methylene blue (MB) aqueous solution and by testing Escherichia coli (E. coli) viability after incubation under UV-B irradiation. E. coli viability experiments indicated that there are two mechanisms of E. coli bacteria inactivation. UV irradiation alone causes rapid damage to the outer membrane of E. coli bacteria. The second mechanism of E. coli inactivation is invoked only with synergistic combination of TiO2 and UV. Acting as photocatalyst TiO2 generates active radicals who initiate the chain peroxidation of organic molecules and within 45 min reduce E. coli bacteria viability by nearly 90%en
