Tio2 And Tio2/wo2 Porous Film Electrodes For Application In Solar Energy Conversion

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/TiO 2 = 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. © 2009 SPIE.7408Fujishima, A., Zhang, X., Tryk, D.A., TiO2 photocatalysis and related surface phenomena (2008) Surf.
