Abstract

In this study, we examined the synthesis and the photoelectrochemical characterization of TiO2 nanotube semiconductor electrodes modified by Prussian Blue (PB) deposits. The PB formation was achieved using cyclic voltammetry. A morphological analysis of the TiO2 nanotubes and the TiO2/PB system was performed using scanning electron microscopy and transmission electron microscopy. Intensity Modulated Photocurrent Spectroscopy (IMPS) measurements were obtained with the goal of determining the charge transfer and recombination constant rates in these systems.
