Anotācija In the present work formation of active nanoporous TiO 2 photocatalysts and their modification with ZnO were studied. TiO 2 nanoporous coatings on Ti foil with surface area 100cm 2 were prepared by using plasma electrolytic oxidation (PEO) method in 0.5M H 2 SO 4 electrolyte and by using 160V DC voltage. For modification of TiO 2 coatings with ZnO spray pyrolysis method where used. After preparation samples were dried and calcined at 400°C for 2h in air. Photocatalytic properties of obtained samples were tested by using degradation method of methylene blue (MB) solution under UV and VIS light illumination. Degradation rate of MB were measured by using spectrophotometer. From obtained results reaction constant (k) in the pseudo first order reaction were calculated. As prepared ZnO modified TiO 2 nanoporous coating photocatalysts are with higher photocatalytic activity with respect to pure TiO 2 nanoporous coating photocatalyst.
