Abstract

PbO2 on different particle scales was deposited potentiostatically onto SnO2＋Sb2O5 layer of Ti substrate. To further investigate the structure and morphology of Ti/PbO2, the electrode was characterized by SEM, XPS and XRD, which shows that the binding energy value of Pb 4f core level for PbO2 is between 138.2 and 138.4 eV, indicating that the surface of electrode is composed of PbO. XRD and XPS data also shows that the bulk is mainly composed of the PbO2. Based on the fact that the electrochemical deposition process is the growth process in different crystal faces, the 3-dimensional growth mechanism of the Ti/PbO2 electrode was suggested.

Key words: lead dioxide electrode, preparation, 3-dimensional growth mechanism, electrochemical deposition
