TiO2 and TiO2/WO3 porous films were deposited onto transparent conducting glass electrodes, resulting in uniform films
consisted of agglomerated particles with average diameters ranging from 50 to 200 nm; Ti, O and W atoms were
homogeneously distributed at the surface of hybrid film. Comparable electrochemical properties were observed in the
dark, with small capacitive currents and similar potentials for O2 and H2 evolution reactions in aqueous solution. Under
polychromatic irradiation, the hybrid film electrode, molar ratio WO3/TiO2 = 12 %, reveled higher photocurrent and
photocatalytic activity for oxidation of phenol and 17-α-ethinylestradiol. The visible light harvesting ability of hybrid
film, with band gap energy estimated as 2.3 eV, and the relative position of conduction and valence band edges that
inhibits charge recombination, should improve its photocatalytic activity for organic pollutant removal.
