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.
