Abstract

The nanocomposite comprising of two simple components – titanium dioxide and Prussian blue – have been synthesized and used for photoelectrode construction. Switching of the photocurrent direction in semiconducting systems upon changes of the electrode potential has been observed. The nanocomposite was characterized by optical spectroscopy and electrochemistry. The structure of the surface complex was modeled using simple quantum chemical models. The behaviour of the photoelectrode was simulated by an adequate electronic circuit. Possible applications of the composite material have been presented.
