Photoelectrochemical Performance of Nanotubular Fe₂O₃-TiO₂ Electrodes under Solar Radiation.

ABSTRACT: Fe₂O₃-TiO₂ materials were obtained by the cathodic electrochemical deposition of Fe on anodic TiO₂ at different deposition times (5-180 s), followed by annealing at 450 °C. The effect of the hematite content on the photoelectrochemical (PEC) activity of the received materials was studied. The synthesized electrodes were characterized by field emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Raman spectroscopy, diffuse reflectance spectroscopy (DRS), Mott-Schottky analysis, and PEC measurements. It was shown that the amount of deposited iron (ca. 0.5 at.%-30 at.%) and, consequently, hematite after a final annealing increased with the extension of deposition time and directly affected th
