Eu doped intermediate layer of SnO₂-Sb with different doping amount were prepared by the thermal decomposition method. The PbO₂was electroplated on the interme diate layer of SnO₂-Sb. The electrochemical performance of the prepared electrodes was evaluated with linear sweep voltammetry( LSV) ; The degradation ability of the prepared electrodes was investigated using p-nitrophenol as a model pollutant; The micrograph, the element composition and the structure of the intermediate layer were analyzed by SEM and XRD, thus the properties of the electrodes were investigate. The results show that, the Eu doping amount has more effect on various performance of electrode. The optimal doping amount is n( Sn) : n( Sb) : n( Eu) = 1 :0 . 1 : 0 . 01 . The electrode at this doping amount has higher oxygen evolution potential and electrocatalysis ability, and better coverage and structure of the electrode. The eletrochemical life of the electrodes achives up to 78 . 6 h.
