A kinetic analysis of the electro-oxidation of ethanol at a platinum electrode in acid medium
TL;DR: In this article, the kinetic laws which govern the oxidation process of ethanol on smooth platinum electrodes in acid medium, electrolyses of ethanol were carried out under different experimental conditions and the influence of the initial ethanol concentration and of the potential plateau of electrolysis were investigated and allowed them to improve their understanding of the reaction mechanism.
Journal ArticleDOI
Cobalt hexacyanoferrate: Compound stoichiometry, infrared spectroelectrochemistry, and photoinduced electron transfer
TL;DR: In this article, the cobalt hexacyanoferrate system, M h Co A k [Fe B (CN) 6 ] l, (where M is an alkali metal cation, and the subscripts h, k, and / are stoichiometric coefficients, and A and B are the formal oxidation states of the Co and Femetal sites in the structure) was shown to contain a rich series of compounds that are interlinked through various redox processes.
Journal ArticleDOI
In-situ FTIR study of the electrocatalytic oxidation of ethanol at iridium and rhodium electrodes
TL;DR: In this article, in-situ Fourier transform IR reflectance spectroscopy has been used to study the electroadsorption and oxidation of ethanol at polycrystalline Ir and Rh electrodes in HClO 4 solutions.
Journal ArticleDOI
Influence of pH on the photochemical and electrochemical reduction of the dinuclear ruthenium complex, [(phen)2Ru(tatpp)Ru(phen)2)Cl4, in water: proton-coupled sequential and concerted multi-electron reduction.

TL;DR: The mechanism to form the doubly reduced, doubly protonated complex, H2P at low pH (< or =7) could be shown to be a two-proton, two-electron process.
Journal ArticleDOI
Modulated reflectance spectroscopy and voltammetry of the sulphide/gold system
TL;DR: In this article, the authors investigated the electroadsorption of sulphide species on gold and the growth of sulphur multilayers using optical and electrochemical techniques in sodium tetraborate buffer as the supporting electrolyte (pH 7.0 and 9.2).
