The characterizations of Ti/SnO2+Sb2O3/PbO2 anodes with SnO2+Sb2O3 as an intermediate layer obtained by way of a polymeric precursor, and using ethylene glycol, ethanol and n-butanol for different precursor solvents were studied. The microstructure, morphology of the SnO2+Sb2O3 layers derived from different precursor solvents and the top PbO2 active layers were examined using by XRD and ESEM. The lifetime and the electro-catalytic activity of Ti/SnO2+Sb2O3/PbO2 anodes with the intermediate layers prepared from different precursors were also assessed by the polarization method and the accelerated lifetime test in 1.0 mol/L H2SO4 solutions. The results showed that the microstructure and, morphology of the SnO2+Sb2O3 layers were correlated to precursor solvents. The intermediate layer made from a polymeric precursor was more compact, homogeneous, possess better surface smoothness, and a higher content of SnO2 and Sb2O3 as compared with that from the other solvents. Thus the Ti/SnO2+ Sb2O3/PbO2 anode prepared from the polymeric precursor had a longer lifetime than that with other solvents, but the intermediate layers prepared from different precursor solvents had little effect on the electro-catalytic activity of Ti/SnO2+Sb2O3/PbO2 anodes.
