Annotation	In this work we have studied the photoelectrochemical behavior of TiO2 anatase electrode in various electrolytes.The TiO2 thin film electrodes were prepared by repeated dip-coating of conductive ITO glass into a homogenous sol.Photoelectrochemical measurements were performed on a three-compartment electrochemical cell.The fundamental mechanism of photo excitation properties of layers consists in the generation of electron-hole pair.Due to a high recombination rate of the photogenerated holes and electrons the measured photo current is low.The recombination can be minimized by addition of oxidizable species.Holes may oxidize organic compounds while electrons migrate to conducting substrate.The measured value of generation photo current depends on adsorption properties of oxidizable substances in the solution, their concentration and the number of TiO2 layers deposited on electrode.
