TL;DR: In this article, basic properties of polyaniline (PA) deposited anodically on platinum electrodes have been studied on the following points: 1) Effect of the mode of electrolysis and supporting electrolytes in the film forming process, 2) Characteristics of charging-discharging processes.
Abstract: Basic behaviors and properties of polyaniline(PA) deposited anodically on platinum electrodes have been studied on the following points. 1) Effect of the mode of electrolysis and supporting electrolytes in the film forming process. 2) Characteristics of charging-discharging processes. 3) Electric conductivity and elemental composition of PA. The different modes of electrolysis do not affect the characteristics of the PA electrode obtained. The growth rate of PA film is 2.7–2.8 times faster in sulfuric acid than in perchloric, nitric or hydrochloric acid. It is indicated that there are two types of doping; one is associated with the acid-base equilibrium between amino or imino group in the film and proton in the solution and the other is associated with the excess charge in the film produced by anodic oxidation. The electric conductivity of PA markedly decreases by the immersion in alkali solutions. The release of doped anion from PA by treating with an alkali solution is confirmed by the elemental analysi...

TL;DR: In this article, the shady state voltammetric behaviior of spherical electrodes of nanometer dimensions (1 and 10 nm) is computed by numerical solution of the Kernst-Planch and Poisson equations, showing that the reversible oxidation or reduction of an electroactive species, assumed to be present in solution at millimolar concentrations, is strongly affected by the electric field from the electrode surface, even in the presence of a large excess quantity of supporting electrolyte (0.5 M).
Abstract: The shady-state voltammetric behaviior of spherical electrodes of nanometer dimensions (1 and 10 nm) is computed by numerical solution of the Kernst-Planch and Poisson equations. The results demonstrate that the reversible oxidation or reduction of an electroactive species, assumed to be present in solution at millimolar concentrations, is strongly affected by the electric field from the electrode surface, even in the presence of a large excess quantity of supporting electrolyte (0.5 M). The assumptions of electroneutrality or diffusion-controlled transport are shown to be generally inappropriate for analyzing the voltammetric response (wave shape and limiting current) of electrodes of dimensions less than ∼0.1 μm

TL;DR: In this article, potential step chronocoulometric methods were used to measure kinetic parameters for the oxidation of ferrocene at platinum vitreous carbon electrodes in acetonitrile, and the experimental activation energy for electron transfer was found to be ΔG≠ (exp) = 0.03 ± 0.02 cm s−1.

TL;DR: The use of a trifluorotris(pentafluoroethyl)phosphate-based ionic liquid, specifically, as supporting electrolyte in acetonitrile solutions affords a wider anodic window, which is attributed to the high stability of the anionic component of these intrinsically conductive and thermally robust compounds.
Abstract: The electrochemical windows of acetonitrile solutions doped with 0.1 M concentrations of several ionic liquids were examined by cyclic voltammetry at gold and platinum microelectrodes. These results were compared with those observed in the commonly used 0.1 M tetrabutylammonium perchlorate/acetonitrile system as well as with neat ionic liquids. The use of a trifluorotris(pentafluoroethyl)phosphate-based ionic liquid, specifically, as supporting electrolyte in acetonitrile solutions affords a wider anodic window, which is attributed to the high stability of the anionic component of these intrinsically conductive and thermally robust compounds.
