Electrochemical Behavior of S-Doped Nanostructured TiO₂ Layer Synthesized with PEO Process for Photocatalytic Applications

Abstract:

Sulfur doped and pure micro-nanoporous TiO₂ film were synthesized with PEO method to produce a film with a high surface area for photocatalysis applications. The effect of applied voltage and electrolyte concentration on the microstructure and photocatalytic properties of the prepared layer were investigated via SEM, XRD, EIS and DRS studies. Electrochemical Impedance Spectroscopy (EIS) was carried out in order to determine the corrosion and electrochemical properties of the produced layer. It was found that although the barrier layer resistance decreases with the voltage, the layers porosity and consequently the surface area increases. Finally the XRD and DRS spectrums were correlated with corrosion and photocatalytic properties in order to find out the optimum parameters of the PEO process to synthesize a layer with desired Properties.
