“…Such organic additives in acid nitrate baths have substantial effects on the PbO 2 layer: (a) Teepol 95 was found to improve the adherence while creating a higher surface area, (b) triton X-100 96,97 improved adhesion and mechanical strength while leading to higher overpotential for O 2 evolution, (c) gelatin and sodium dodecylsulfonate 97 modified morphology and increased the a-PbO 2 content of the deposit, (d) polyvinyl pyridine 98 could be used to control both the morphology and crystal size. Other common additives are long chain, tetraalkylammonium ions 99 and these have found application in the soluble lead acid battery. 89,100-107…”

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).

“…An intense interest in the PbO2-Pb(II) redox couple has existed because of the use of PbO2 in lead-acid batteries (7)(8)(9), as well as for anodes in electrosynthesis (10)(11)(12)(13). Secondary interest in the redox couple has resulted because the deposition of PbO2 is a unique model for testing electrocrystallization theories (14)(15)(16)(17)(18)(19)(20)(21).…”

The electrodeposition of 13-PbO2 from HC104 solutions of Pb(II) at an Au rotated disk electrode (RDE) was studied as a function of applied potential, rotational velocity, and the concentrations of HC104 and Pb(II). A long induction period (i.e., i = 0) is associated with high acidity, low concentration of Pb(II), and high rotational velocity. Following the induction period, the current rises to a steady-state value which is significantly lower than the mass transport-limited value for Pb(II). The steady-state value of electrode current decreases as rotational velocity is increased, contrary to expectations for a mass transport-controlled process at a RDE. The generation of a soluble intermediate species is proposed to account for these observations. Repeated cycles of deposition and stripping of PbO2 at the Au RDE results in a decreasing induction period for subsequent PbO2 deposition. This is concluded to result because a Pb(II) ad-layer (possibly PbO) is formed which is stabilized by interaction with the Au substrate and is not dissolved following the negative potential scan to 0.3V. The original state of the clean Au surface is regenerated by cathodic He(g) evolution, chemical stripping with H202 or KMnO4, or by mechanical abrasion.) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.

“…Polyvinyl pyridine could be used to control both the morphology and crystallite size (Ghasemi et al, 2007). Other additives such as tetraalkylammonium ions were also applied in lead dioxide anode preparation process (Ghanasekaran et al, 1976;Pletcher & Wills, 2004). Low et al (2009) reported that a highly reflective lead dioxide electrode could be prepared by adding hexadecyltrimethylammonium chloride or bromide to the electroplating bath.…”
