AB  - Electrocatalysis is the science exploring the rates of electrochemical reactions as a function of the electrode surface properties. In these heterogeneous reactions, the electrode does not only accepts or supplies electrons (electron transfer), as in simple redox reactions, but affects the reaction rates interacting with reactants, intermediates, and reaction products, i.e., acts as a catalyst remaining unchanged upon its completion. The term electrocatalysis, an extension to electrochemistry of the term catalysis (Greek kata (down) and lyein (to let)), was apparently first used in 1934[1]. The beginning of intensive research in this area can be traced back to early 1960s in connection with the broadening fuel cell research. Many electrocatalytic reactions have great importance. These include hydrogen, oxygen, and chlorine evolution; oxygen reduction oxidation of small organic molecules suitable for energy conversion (methanol, ethanol, formic acid); and reactions of organic syntheses. Important features of electrocatalytic reactions, facilitated by the application of the electrode potential, include (i) high reaction rates that can be achieved, (ii) high selectivity at defined potentials, and (iii) the unique direct energy conversion in fuel cells that are likely to become one of the major sources of clean energy. The main events in an electrocatalytic reaction are adsorption/desorption, electron transfer, and bond breaking/formation.

AB  - Oxygen reduction reaction has been studied on Pt low index planes in 0.1 M and 85% H3PO4 using hanging meniscus rotating disc electrode technique. The first-order kinetics of O2 reduction reaction was found for all three surfaces in a four-electron process with the first electron transfer rate determining in both 0.1 M and 85% H2PO4 solutions. Catalytic activity for O2 reduction follows the sequence Pt (110)>Pt (100)>Pt (111). Structural dependence is predominantly determined by the adsorption of phosphoric acid anions, which is strongly structure-dependent on Pt surfaces.

AB  - Oxygen reduction on gold single crystal electrodes of various orientations, Au(hkl), in 0.1 M NaOH was studied by rotating disk electrode and rotating disk ring electrode techniques, with a goal to correlate the physical and chemical properties of the electrode surface with its catalytic activity. The characterization of the state of the electrode surface and the interface was carried out by cyclic voltammetry and differential capacity measurements. The geometrical arrangement and symmetry of surface atoms, and the presence of chemisorbed OH- anions, were found to play a key role in determining the catalytic properties of Au(hkl) surfaces for O2 reduction. It was proposed that chemisorbed anions act as a precursor for the dissociative adsorption of molecular oxygen or for chemisorption of reaction intermediate, catalyzing the 4e--reduction of O2.

AB  - Oxygen reduction on the Au(100) face was studied by the rotating disk-ring electrode technique in solutions of anions which adsorb strongly on gold (HSO4-/SO42- and/or OH-) over the entire pH range. The specific adsorption of OH- anions, which is a pH dependent process, is found to play the key role in determining the reaction pathways. In the absence of OH- adsorption, for pHs below 6, the reduction of O-2 begins as a 2e-process. Due to the increase in local pH during O-2 reduction, the reaction pathway turns into a 4e-reduction at a certain potential depending on the pH of the solution. For pHs higher than 6, O-2 reduction begins as a 4e-process in the potential region where specifically adsorbed OH- anions are present.

AB  - Oxygen reduction has been studied in 0.1 M HClO4 on the platinum low index surfaces, employing a hanging meniscus rotating-disk technique. A special cleaning procedure has been developed to remove impurities from the surface prior to the oxygen reduction measurements. Oxygen reduction was found to be sensitive to the crystallographic orientation of the platinum electrode surface. The activity for oxygen reduction discerned from the half-wave potential decreases in the sequence (110) & >; (111) & >; (100). The reaction proceeds on all well-ordered low index planes with exchange of four electrons per O2 molecule. Tafel slopes of −120 mV per decade at high current densities and −60 mV / per decade at low current densities were found for all three planes at room temperature. Oxygen-containing species chemisorbed on platinum appear to be the cause of the change in the Tafel slope.

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  - Hydrogen adsorption on single-crystal platinum low-index and stepped surfaces was studied in 0.1 M and 0.01 M NaOH solutions. A strong dependence on the crystallographic orientation of the electrode surface was found. The multiple states of hydrogen were correlated with the symmetry of surface sites. The data for the stepped surfaces were found to be useful in explaining the nature of processes occurring on the low index surfaces. Several strong indications were found for the nature of the so-called "butterfly" peak, indicating that it is due to adsorption of the hydroxil species rather than to hydrogen adsorption. Indications for hydrogen adsorption on Pt(111) in the H2 evolution region was found by impedance measurements. An effort was made to identify the multiple adsorption states for Pt(100). Hydrogen adsorption on the step sites for surfaces from all three crystallographic zones was identified and found to be proportional to the step density.

abstract = "Hydrogen adsorption on single-crystal platinum low-index and stepped surfaces was studied in 0.1 M and 0.01 M NaOH solutions. A strong dependence on the crystallographic orientation of the electrode surface was found. The multiple states of hydrogen were correlated with the symmetry of surface sites. The data for the stepped surfaces were found to be useful in explaining the nature of processes occurring on the low index surfaces. Several strong indications were found for the nature of the so-called "butterfly" peak, indicating that it is due to adsorption of the hydroxil species rather than to hydrogen adsorption. Indications for hydrogen adsorption on Pt(111) in the H2 evolution region was found by impedance measurements. An effort was made to identify the multiple adsorption states for Pt(100). Hydrogen adsorption on the step sites for surfaces from all three crystallographic zones was identified and found to be proportional to the step density. A comparison with hydrogen adsorption in acid solutions was made for some surfaces.",

AB  - Reaction kinetics of glucose oxidation on single-crystal platinum electrodes has a pronounced structure sensitivity. Quasi-steady-state measurements show Tafel slopes of 120 mV per decade for Pt(111), but 60 mV per decade for Pt(100). The isotope effect indicates that the first reaction step involves the oxidation of the aldehyde hydrogen atom bound to the C1 carbon atom, which is the rate-determining step for both surfaces. The reaction orders with respect to glucose are unity for Pt(111), but 0.5 (first peak) and close to zero (second peak) for Pt(100). The strongly bound intermediate on Pt(111) appears to be gluconolactone, but CO for Pt(100). The reaction mechanism for Pt(111) involving a slow first charge transfer step fits the observed kinetic parameters. Problems in determining the mechanism for Pt(100) are discussed, as well as the catalytic decomposition of glucose. Within this framework the oxidations of fructose, gluconolactone and gluconic acid were also investigated.

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  - Hydrogen and bisulphate adsorption at platinum single crystal surfaces from the [ITO] zone is
strongly dependent on the crystallographic orientation of the electrode surface, which is similar to that
found earlier for the [llO] zone. For the purposes of comparison, some experiments were performed with
non-adsorbing perchlorate acid solutions. The multiple states of hydrogen adsorption can be correlated
with symmetry of surface sites and the nature of the adsorbed oxi-anions. All stepped surfaces
investigated from this zone have one sharp peak at -0.175 V which is due to a coupled desorption of
bisulphate and hydrogen adsorption from the sites with the (110) symmetry. The surfaces of the
n(llO)-(lll) type behave as the surfaces denoted (n -1X110)-3(111) since the three atom long terrace is
“seen” by bisulphate and hydrogen.
Bisulphate anions are more strongly adsorbed at the steps than at the (111) oriented terraces, The
latter process occurs at more positive potentials than the adsorption at steps and it is affected by anions
at the step sites. The structure in the electrolyte solutions has been discussed.

AB  - The oxidation of ethylene glycol (EG) has been studied on platinum single-crystal surfaces in 0.1 M NaOH. A strong structural dependence of the reaction kinetics was found for all 12 single-crystal orientations investigated. The onset of the reaction occurs in the sequence Pt (110) > Pt (100) ≈ Pt (111). However, the peaks of the voltammetry curves for the low-index planes decrease in the order (111) > (110) > (100). Either the (111) or the (100) oriented steps cause a decrease in the activity of the (111) plane. Surfaces vicinal to the (100) plane exhibit a higher activity than Pt (100). The (111) oriented steps in the Pt (110) plane cause an increase in activity, while the (100) oriented steps decrease it. A parallelism between PtOH layer formation and the onset of the oxidation of EG was found which indicates that the reaction involves interaction of the adsorbed and dehydrogenated EG with Pt(OH)ads species.

AB  - Electrochemical oxidation of D-glucose has been studied in 0.1 M NaOH on single crystal platinum electrodes with thirteen different orientations. The reaction rate depends strongly on the crystallographic orientation of the electrode surface. For most of the surfaces investigated, three voltammetric peaks were observed in the potential region of hydrogen adsorption, the double layer region and the region of anodic film formation. The most active surface is Pt(111). The poisoning adsorbates seem to be less strongly adsorbed on this plane than on Pt(100) or Pt(110). The (100) and (111) oriented steps cause a decrease of the activity of Pt(111). A strongly bound species appears to be adsorbed preferentially on the step sites. Its oxidation was found to coincide with the Pt(OH)ads layer formation.

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  - Oxide formation and anion adsorption have been studied on gold single crystal stepped surfaces. Most of the measurements were performed in sulphuric and some in perchloric acid solutions by cyclic voltammetry and by double layer capacity measurements. A pronounced structural sensitivity of both oxide formation and anion adsorption was found. The effects of the terrace orientation, step orientation and step density are reflected in voltammetry and the double layer capacity measurements. A systematic dependence of both processes on step density was found and their interrelation is discussed. The results contradict some gas-phase data reporting no critical role of steps in oxygen chemisorption on gold. A correlation between the relative surface energy of gold single crystals and the peak potentials of the initial stage of oxide formation was found.

AB  - The adsorption of hydrogen and sulphuric acid anions has been studied on single-crystal platinum stepped surfaces from the [110] zone. Both processes depend on the orientation of the electrode surface. The multiple states of hydrogen adsorption can be correlated with the nature and density of the adsorption sites. There is a negligible effect of adsorbate-adsorbate interaction. The voltammetric profiles are in a wide potential range determined by bisulphate and sulphate adsorption/desorption. A sharp peak found in voltammetry is associated with hydrogen adsorption in the step sites, composed of the (100)-(111) step-terrace combination, concurrent with sulphate desorption. Bisulphates and sulphates are strongly adsorbed in the trigonal sites in the step, which can be formed from the steps and terraces of different orientations from this zone. The exact position of the adsorbed hydrogen atoms and anions is discussed. A comparison with the adsorption in HClO4 is given for some surfaces.

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.

AB  - The oxidation of formic acid and hydrogen adsorption have been measured on platinum single-crystal stepped surfaces with five orientations. A pronounced structural sensitivity of both reactions has been found. They show a sensitivity to the terrace orientation, the density of steps and to the step orientation The surfaces which are blocked for reaction by intermediates formed in the oxidation of formic acid, as the Pt(100) and Pt(110) surfaces are, become more active upon introduction of steps. The surface which are not blocked, i.e. the Pt(111) surface, become less active upon introduction of steps because more active steps increase their activity for the "wrong" reaction - the formation of blocking intermediates. Preliminary data on hydrogen adsorption show the possibility of using this reaction as a check of the degree of order and orientation of sigle-crystal Pt surfaces.

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.
