Abstract

Effect of nanosized particles of lead dioxide on the potential and current of cyclic voltammetry peaks in sulfuric acid media was studied. Nanomaterial was synthesized by pulsed current electrochemical method. Material characterization was done by XRD, SEM and ICP. Electrochemical characterization was carried out by cyclic voltammetry in sulfuric acid solutions. The electrochemical parameters of
-2 on the lead substrate were further calculated by cyclic voltammetry. Under the selected Keywords: Cyclic voltammetry Pulsed current; Nanostructure; Lead dioxide; Particle size; Electrochemical behavior;   PbO conditions the anodic and cathodic peak currents were linear with lead dioxide particle size over the range lower than 100 nm by cyclic voltammetry. The obtained results also showed a good linear relation between anodic peak potential with particle size. Smaller particles increase the currents of reduction and oxidation peaks and, decrease the oxidation potential for lead dioxide formation. It was not seen a regular relationship between particle size and potential of reduction peak. An attempt to understand the particle size effect on the shift of electrochemical parameters based on the particle size and morphology of lead dioxide.
