Annotation	Heterogeneous photocatalysis is based on the reaction between the light excitated semiconductor and oxidizable compound adsorbed on the catalytic surface. This work reports the photoelectrocatalytic oxidation characteristics of carboxylic acids on the TiO2 sol-gel thin-film electrode by using electrochemical techniques. The influence of the thickness of the films on photoactivity and the various concentrations of oxalic, formic and acetic acid in the supporting electrolyte were investigated. The effect of the used mono- and dicarboxylic acids on the electrode behaviour for possible application as sensors has been also studied. The surface characteristics of TiO2 films were determined by XRD, SEM and AFM analyses and the photoexcitation properties of nanoparticulate layer electrode were determined by cyclic and linear voltammetry, amperometry and open circuit potential (OCP).
