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. |
