%X IrO2-Ta2O5 oxide anode was prepared by coating oxide on titanium substrate which has been pretreated by sandblast and oxalic acid etching. ESEM, polarization curve and EIS indicated that the corrosion rate of the substrate and the loading of the oxide coating (i.e. Ir content) increase with etching time at the initial stage and then decrease. The oxide coating on the substrate pretreated by suitable etching pretreatment is of a uniform and compact surface which has large electrochemical active surface area, fine electrocatalytic activity for oxygen evolution and high stability.
