“…We are not aware of any substantial reviews of lead dioxide electrodes in recent years. The history and fundamental chemistry of PbO 2 anodes is covered in 1972 and 1986 reviews by Hampson,5,11 a 1979 book by Kuhn, 8 a 1990 Chemical Review of electrode materials 12 and a more recent chapter by Salkind et al 10 The period since the last review has seen major developments in lead dioxide coatings.…”

Lead dioxide coatings on inert substrates such as titanium and carbon now offer new opportunities for a material known for 150 years. It is now recognised that electrodeposition allows the preparation of stable coatings with different phase structures and a wide range of surface morphologies. In addition, substantial modification to the physical properties and catalytic activities of the coatings are possible through doping and the fabrication of nanostructured deposits or composites. In addition to applications as a cheap anode material in electrochemical technology, lead dioxide coatings provide unique possibilities for probing the dependence of catalytic activity on layer composition and structure (critical review, 256 references).

“…On the one hand, earlier studies remained inconclusive in regards to whether it is fully stoichiometric with respect to oxygen [3][4][5] or not; on the other hand, according to recent studies based on theoretical calculation, 6-8 the conductivity is due to oxygen vacancies.…”

The properties of electrodeposited PbO 2 are sensibly influenced by the deposition current and temperature. In particular, tritium radiotracer measurements demonstrated that protons were incorporated into the bulk of an oxide film and on its surface. The degree of hydration increased with increasing current and decreased with temperature, and was related to the morphological characteristics of the oxide, such as roughness measured by changes in the double layer capacity. Conversely, the amount of hydrogen had negligible effects on the number of free carriers as evaluated from Mott-Schottky plots. The hydration degree of the surface seems to be an important factor influencing electrocatalytic processes at high potentials, such as O 2 evolution and O 3 formation. On less hydrated, more crystalline PbO 2 surfaces, the first process was inhibited and accordingly, the second was favored.

“…Although platinum and graphite have been used as electrode materials, lead dioxide coated onto inert substrates has become popular due to its good electrical conductivity, favorable overpotential for oxygen evolution and high chemical inertness [1][2][3]. PbO 2 has been used as an anode material for the generation of ozone [4][5][6] and in wastewater treatment [7][8][9]. The 3-D nucleative growth of PbO 2 has been found to follow a similar pattern on Pt [10], SnO 2 [11,12], glassy carbon [13][14][15] and Au [16,17].…”
