Influence of Fluoride Ion on the Electrochemical Properties of Al/β-PbO2 Electrode

Al/α-PbO2/β-PbO2 electrodes doped with fluoride ion (NaF) were prepared by anodic co-deposition in order to investigate the influence of NaF dopants on the properties of Al/α-PbO2/β-PbO2 electrodes. In our work, we found fluoride ion will benefit for the crystallization of β-PbO2 and change the crystallite size, crystal structure, enhance the catalytic activity, and even change the mechanism of the reaction in the oxidation of the material. The presence of NaF in the β-PbO2 electrolyte could enhance the electrochemical properties of the coating and therefore make itself as a superior anode material.
