Abstract:EuBr3, Eu(NO3)3, EuCl3, Eu(ClO4)3, Eu(AC)3 doped Sb-SnO2/Ti electrodes were prepared by thermal decomposition. The properties of electrodes for the oxidation of ethanol and the electro-catalytic decomposition of a model pollutant (methyl orange, methylene blue) were investigated. Electrodes were characterized by cyclic voltammetry, X-ray diffraction, scanning electron microscope, and X-ray photoelectron spectroscopy. It is suggested that various Eu salts doped Sb-SnO2/Ti electrodes show different catalytic properties. Eu(ClO4)3 doped electrodes show the best effect for degradation of methyl orange, EuCl3 doped electrodes provide the best degradation of methylene blue, and as for electric catalytic oxidation ethanol, Eu (NO3)3 doped electrodes show the highest catalytic activity
