In this study, the critical deposition parameters of electrophoretic deposition (EPD) of materials are reviewed and its potential use in the production of thin films for photocatalytic oxidation of organic compounds are analyzed. In a case study, EPD was used to obtain titanium dioxide (TiO2) coatings on glass substrates using colloidal suspensions of TiO2 nanoparticles in ethanol with addition of iodine. The deposit parameters were optimized to obtain homogeneous and strongly adhered TiO2 thin films. The factors that determine the efficiency of TiO2 in the decomposition of organic contaminants are also presented.
