Abstract This paper describes the formation and characterization of transparent mixed α-Fe2O3/TiO2 nanotubular layers. Mixed metal oxide nanostructured layers were prepared by two steps. At first, Fe-Ti alloy layer was prepared by a high-powered impulse magnetron sputtering (HiPIMS) deposition on fluorine doped tin oxide (FTO) glass substrate and then electrochemically oxidized in fluoride containing electrolyte. Prepared alloy layers and anodized layers were characterized by SEM/EDS, μXRD, UV–vis spectroscopy. Anodized layers consist of hematite nanotubes with the length around 1400 nm and expansion factor close to 2.5. Titanium is present as amorphous TiO2. Photoelectrochemical properties of transparent mixed α-Fe2O3/TiO2 layer in aqueous electrolyte were evaluated. Presence of Ti in the Fe-Ti alloy results in a significant increase in photoresponse.
