Abstract

Electrocatalytic anodes act as key function of electrocatalytic oxidation process for the removal of toxic or biorefractory materials. The characteristics of the anodes, such as potential for oxygen evolution, electric resistance, crystal size of the coating or the service life etc., have important impacts on the behavior of the electrodes. Titaniumbased tin dioxides electrode Ti ∕ SnO2 found a kind of catalytic material with high oxygen evolution potential which related to the catalytic ability with the degradation of toxic material for aqueous wastes removal Four kinds of rare earth (Dy, Eu, Nd and Gd) were selected as doping agents to research the relationship between the electrocatalytic properties and the degradation pathway for organics degradation with the inner structure of the SnO2 crystals. The crystal structure of the electrode materials influence the properties of the anodes in many aspects and should be very important to understand the interplay mechanism for developing new kinds of catalytic electrodes.
