V 2 O 5 -TiO 2 porous layers were synthesized via micro-arc oxidation for the first time. The effect of the applied voltage on morphology, composition, and photoactivity of the layers was investigated. The layers, which consisted of anatase, rutile, and vanadium pentoxide phases, revealed an enhanced photo-activity. About 93% of methylene blue solution was degraded on the synthesized layers after 120 min UV-irradiation with a reaction rate constant of k = 0.0228 min -1 . The band gap energies of the vanadia-titania and pure titania layers were calculated as 2.56 and 3.39 eV, respectively.
