Electrodeposition of fluorine-doped PbO2

The electrocatalytic properties of PbO2 may be increased by incorporation of some ions such as F−. In this review, the preparation of fluorine-doped PbO2 in the presence of some additives of fluorine-containing compounds (F−, potassium salt of nonafluoro-1-butanesulfonic acid C4F9O3SK and Nafion®) i...

Description
Summary:The electrocatalytic properties of PbO2 may be increased by incorporation of some ions such as F−. In this review, the preparation of fluorine-doped PbO2 in the presence of some additives of fluorine-containing compounds (F−, potassium salt of nonafluoro-1-butanesulfonic acid C4F9O3SK and Nafion®) is reported. The mechanism of electrodeposition is discussed. The amount of additives in the deposit depends on the experimental conditions: potential, current density and charge of additive species in the plating solution. The physicochemical properties of doped oxide are very different from those of undoped oxide, accounting for the different electrocatalytic activity of the materials.
