Abstract

The dimensionally stable anode(DSA）has been developing quickly in recent years. The IrO2+SnO2/Sb2O3+SnO2/Ti

IrO2+Ta2O5/Sb2O3+SnO2/Ti and IrO2+SnO2/Ti coated electrodes were prepared by the thermal decomposition method. The properties of the coated electrodes for oxygen evolution were studied by linear sweep voltammetry

electrochemical impedance spectroscopy and accelerated corrosion test. Pb and its alloy electrodes were also used in contrast experiment. Distribution of chemical elements and surface topography were observed by EDX and SEM. The effects of electrolytic result were investigated with the coated electrodes

Pb and its alloy electrodes as anode in electrolytic synthesis of succinic acid. The results showed that the cell voltage reduced by 0.5—0.7 V and current consumption of electrolysis decreased by almost 10% when the coated electrodes instead of Pb and its alloy electrodes were used in the electrolytic process. Based on the comparison of three coated electrodes

the SnO2-Sb2O3 interlayer could improve the properties of the coated electrodes for oxygen evolution and the service life of the coated electrodes in H2SO4 solution. The IrO2+SnO2/Sb2O3+SnO2/Ti electrode displayed favorable performance for oxygen evolution and the working life exceeded 1456 days as the SnO2 replaced Ta2O5 in the active coating of electrode. Although cell voltage and current consumption of electrolysis were a little bit higher

IrO2+SnO2 coated electrode was more cost effective because of replacement of noble metal in active coating.
