AB  - The kinetics of oxygen reduction on the Au(111) surface in acidic solution has been re-examined by means of a rotating disc electrode technique. Its vicinal Au(332) = Au[6(111) × (111)] surface has been chosen to examine the role of a small density of steps as active sites. The increase of the average surface energy, caused by the presence of steps on the Au(332) face, causes a slight shift of the half-wave potential to a more positive value, compared to the Au(111). The reaction on Au(111) is kinetically hindered in the whole potential region up to hydrogen evolution. The presence of steps on the Au(332) face apparently causes the kinetic limitations to be lifted. The kinetics of oxygen reduction on the Au(332) face in alkaline solution has been studied by means of a rotating disc-ring method. The mechanism of the reaction has been found the simplest among all the faces of Au investigated so far. In the kinetic and mixed control regions the reduction proceeds through the simplest 2e-series pathway. At large overpotentials, a 4e-reduction occurs, whose extent depends on the potential, with a surface diffusion of HO-2a as a rate determining step. No splitting of the OO bond has been found. A map of the reaction pathways for the whole potential range of oxygen reduction has been constructed.

AB  - The kinetics of oxygen reduction have been studied on Au (100) and vicinal Au (910) and Au (11, 1, 1) faces in 0.1 M NaOH by a rotating disc-ring method. A very high activity of these surfaces for O2 reduction was demonstrated. The reaction involves a four-electron reduction without HO2- reaching the ring electrode in the presence of the AuOH-(1-λ2) layer on the Au (100) surface. At more negative potentials, as θAuOH → 0, a four-electron reduction takes place in an interactive pathway, followed by a two-electron series pathway and, at very large overpotentials, by a four-electron series pathway. The first electron transfer is the rate-determining step for all three faces. For vicinal faces, the region of the four-electron reduction is reduced due to the smaller region of AuOH formation. Evidence for the surface diffusion of HO2- was found from analysis of the disc-ring data. There were also indications for the splitting of the OO bond by AuOH in the region of the four-electron reduction. Maps of the reaction pathways have been constructed.

AB  - Oxygen reduction has been studied in alkaline solution on a ruthenium electrode modified by thallium and lead adsorbates. A partially oxidized ruthenium electrode is inactive for oxygen reduction. Thallium and lead adsorbates cause pronounced changes on the ruthenium surface giving rise to a four electron-reduction of oxygen. Disc-ring electrode measurements show a predominant direct four electron-reduction, with a first charge-transfer rate determining step. Mass fractions of various reaction pathways have been calculated and the model explaining a direct four electron-reduction discussed. Once activated, ruthenium retains its activity even in the absence of thallium and lead ions in solution phase.

AB  - The oxidation of formaldehyde on gold has been studied by a rotating disc-ring method. Hydrogen evolved on the disc was possible to detect on the Pt ring electrode. The reaction scheme was proposed, and expressions for the disc and the ring current were evaluated. Experimental results fit well diagnostic criteria for a series scheme of the oxidation of formaldehyde. The partial currents associated with the oxidation of formaldehyde to formate and hydrogen to water have been calculated. The results illustrate the possibility of using the disc-ring method in elucidation of the mechanisms of oxidation of small organic molecules when a proper selection of the ring electrode and its potential is made.

AB  - Oxide formation and oxygen reduction on gold have been investigated with single crystal electrode surfaces of various orientations. Both reactions show sensitivity to the surface orientation, presence of steps, their density and orientation. The initial stages of oxide formation can be correlated with calculated relative surface energy. Anions exert a pronounced effect on oxide formation. The activity for oxygen reduction can be correlated with the same surface property except for Au(100). Structural effect from this particular plane outweighs the electronic effects. No correlation for alkaline solutions was found. Rotating ring-disc measurements show no hydrogen peroxide generation Au(100) in the presence of almost neutral AuOH-(1 - λ)on the surface. This makes it the most active electrocatalyst for oxygen reduction in alkaline solutions. At more negative potentials (no AuOH on the surface) a series mechanism up to the peroxide stage is operative. The Au(311) plane also shows a high activity dependent on AuOH-(1 - λ). Data for both reactions clearly demonstrate that each crystallographic orientation gives an electrode surface with distinct electrochemical properties.

AB  - Oxygen reduction was studied for the first time using a single crystal electrode in a rotating disc-ring arrangement. The Au (311) surface shows a complex behaviour, with a very high activity in certain potential regions. The first electron transfer is rate determining in the region of 4-electron reduction. As with Au (100), a 4 e- reduction changes into a 2 e- process, which reverts back to a 4 e-reaction at very negative potentials. Based on a general reaction scheme of O2 reduction, a map of the operating potential dependent reaction pathways was constructed. Nearly 60% of the mass flux of O2 undergoes a direct reduction to OH- in the region of mixed control. The high activity of Au (311) was ascribed to a high step density and AuOH present on its surface.

AB  - Some of the well-known criteria for analysing rotating disk measurements have been examined. It has been shown that for reactions with complex mechanisms the number of electrons exchanged per reactant is a function of the potential of the electrode and cannot be evaluated theoretically in a simple manner. Also, it has been shown that none of the prescribed methods of obtaining the overall reaction order will give a proper answer unless the number of electrons is known a priori. This couling of the number of electrons exchanged and the overall reaction order is inherent in the rotating disk experiment. Therefore the use of the rotating disk in elucidating the overall kinetic parameters of the process is much more limited than previously thought.

Therefore the use of the rotating disk in elucidating the overall kinetic parameters of the process is much more limited than previously thought.",

AB  - A general scheme of oxygen reduction is given and analysis of the disk-ring measurements is performed. Expressions for the diagnostic criteria for such a scheme have been derived and their implications are discussed. The existence of superoxide and oxygen ions and the interaction of the series and direct paths have been assumed in postulating the scheme.

The possibilities and limitations of the disk-ring measurements in the mechanistic study of oxygen reduction are discussed together with a re-evaluation of some well-accepted criteria which are shown to be misleading. New definitions and terminology for different pathways of O2 reduction are proposed.

AB  - The kinetics of oxygen reduction have been studied on a ruthenium electrode in alkaline solutions using the rotating disc and rotating disc-ring methods. The reaction kinetics and mechanism were found to depend on the oxidation state of the ruthenium surface. For a surface having up to two monolayers of oxide a "parallel" mechanism of O2 reduction has been found, which goes predominantly through a four-electron direct reduction to OH-. All the rate constants of the O2 and HO-2 reactions, including those of the adsorption equilibrium of HO-2 on the Ru surface, have been determined. No catalytic decomposition of HO-2 was found. Although the Tafel slope is higher than -120 mV/dec it appears that an initial electron exchange is the rate-determining step. The kinetics are slower on a Ru surface with a thicker oxide layer. The mechanism of the reaction is also different, showing a potential-dependent ratio of the rate constants for a direct and series reduction of O2 and a catalytic decomposition of HO-2.

AB  - The kinetics and mechanism of O2 reduction on an Ru electrode in acid electrolytes have been measured by using a disc—ring method. The reaction proceeds through a “parallel” mechanism with the exchange of approximately four electrons. It shows a pronounced dependence on the oxidation state of the Ru surface. A catalytic decomposition of H2O2 does not occur on the surface obtained at potentials E > 0.0 V. Tafel slopes, some rate constants and reaction orders for O2 and H2O2 reduction have been determined. Calculated rate constant for a direct reduction of O2 (k1) is higher than k2, the reduction with the H2O2 intermediate. The experimental value of k3, the H2O2 reduction, is lower than k1 and k2 at E > 0.05 V. The Tafel slope for O2 reduction with the value higher than 120 mV has been obtained.
