Abstract	Four types of TiO2 thin-film electrodes were fabricated from TiO2 and Fe(III)doped TiO2 sols using a layer-by-layer dip-coating technique.Electrodes fabricated were TF (pure TiO2 surface,Fe(III)-TiO2 bottom layer),FT (Fe(III)-TiO2 surface,pure TiO2 bottom layer),TT (both layers pure TiO2)and FF (both layers Fe(III)-TiO2).The photoelectrochemical behavior of these electrodes was characterized using linear sweep voltammetry (LSV),electrochemical impedance spectroscopy (EIS)and steady-state photocurrent measurements in aqueous 0.1 mol L-1 NaNO3 containing varying concentrations of glucose or potassium hydrogen phthalate (KHP).EIS and LSV results revealed that exciton separation efficiency followed the sequence of TF > TT > FT > FF.Under a constant potential of +0.3 V,steady-state photocurrent profiles were recorded with varying organic compound concentrations.The TF electrode possessed the greatest photocatalytic capacity for oxidizing glucose and KHP,and possessed a KHP anti-poisoning effect.Enhanced photoelectrochemical performance of the TF electrode was attributed to effective exciton separation because of the layered TF structure.
