Thin films of ZnO, ZnO coated with TiO2 and ZnO modified with titania were prepared by using simple spray pyrolysis of zinc and titanium containing solutions. The photocatalytic activity of the obtained films was determined by degradation of MB solution under UV and simulated solar illumination. The photocatalytic activity of ZnO/TiO2 films depended on the content of titania, substrate surface roughness, surface area and deposition cycles. The highest activity under simulated solar light was detected for ZnO films containing 3 wt.% of TiO2.
