AB  - The poor activity and stability of electrode materials for the oxygen evolution reaction are the main bottlenecks in the water-splitting reaction for H2 production. Here, by studying the activity–stability trends for the oxygen evolution reaction on conductive M1OxHy, Fe–M1OxHy and Fe–M1M2OxHy hydr(oxy)oxide clusters (M1 = Ni, Co, Fe; M2 = Mn, Co, Cu), we show that balancing the rates of Fe dissolution and redeposition over a MOxHy host establishes dynamically stable Fe active sites. Together with tuning the Fe content of the electrolyte, the strong interaction of Fe with the MOxHy host is the key to controlling the average number of Fe active sites present at the solid/liquid interface. We suggest that the Fe–M adsorption energy can therefore serve as a reaction descriptor that unifies oxygen evolution reaction catalysis on 3d transition-metal hydr(oxy)oxides in alkaline media. Thus, the introduction of dynamically stable active sites extends the design rules for creating active and stable interfaces.

AB  - A remaining challenge for deployment of proton-exchange membrane fuel cells is the
limited durability of Pt-nanoscale materials that operate at high voltages during the
cathodic oxygen reduction reaction. In this work, atomic-scale insight into well-defined
single crystalline, thin-film, and nanoscale surfaces exposed Pt dissolution trends that
governed the design and synthesis of durable materials. A newly defined metric, intrinsic
dissolution, is essential to understanding the correlation between the measured Pt loss,
surface structure, size and ratio of Pt-nanoparticles in carbon support. It was found that utilization of Au underlayer promotes ordering of Pt surface atoms towards (111)- structure, while Au on the surface selectively protects low-coordinated Pt sites. This
mitigation strategy was applied towards 3 nm Pt3Au/C nanoparticles, resulting in
elimination of Pt dissolution in liquid electrolyte, including 30-fold durability improvement
vs. 3 nm Pt/C over extended potential range up to 1.2 V.

AB  - Ability to utilize structure-function relationship in the design of electrocatalysts relies on fundamental understanding of physicochemical processes at the topmost surface. It has been demonstrated that reaction rate for majority of electrochemical reactions exhibit notable dependence on geometric arrangement of surface atoms due to varying levels of binding strength between different atomic structures and adsorbate molecules. Control of surface structure at nanoscale is being investigated here through a thin film approach. The surface characteristics of electrochemically deposited Pt thin films were probed for electrooxidation of small organic molecules such as formic acid and methanol. The low-index Pt single crystal electrodes were used for reactivity benchmarking which later guided thermal annealing processes, and ultimately, fine tuning of the ratio between (1 1 1) and (1 0 0) surface facets on Pt thin films. The tailored thin film structure is responsible for significant activation of both formic acid and methanol oxidation reactions, which justifies the approach.

AB  - The formic acid oxidation on Pt/Ru nanoparticles in acid solution over the temperature range 298-333 K has been studied by thin-film rotating disk method (RDE). Transmission electron microscopy in combination with scanning tunneling microscopy was used to determine the size (4.3 +/- 0.3 nm) and shape (cuboctahedral) of the particles. Kinetic analysis revealed that at elevated temperatures (313 K, 333 K) the reaction rate is much higher than at room temperature (295 K), indicating that formic acid oxidation on supported Pt/Ru catalyst is a highly activated process. Based on experimental kinetic parameters we propose that the HCOOH oxidation on the PtRu alloy most likely follows a dual pathway, but the branching ratio is still very high, i.e. Pt-like. The principal effect of opening the dehydration channel at steady-state (via the presence of Ru in the surface) is to lower the coverage of COads on Pt sites and permit the dehydrogenation path to increase in rate.

AB  - The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% PtRu (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode (RDE) method. It was found that the activity of Pt and PtRu for methanol oxidation is a strong function of pH of solution and temperature. The kinetics are much higher in alkaline than in acid solution; at 333 K, a factor of 30 for Pt and a factor of 20 for Pt2Ru3 at 0.5 V. The pH effect is attributed to the pH competitive adsorption of oxygenated species with anions from supporting electrolytes. The activity of Pt and Pt2Ru3 catalysts at 333 K is higher (a factor of 5) than at 295 K. Irrespective of pH, only negligible differences in the kinetics are observed between Pt and on high Ru content Pt alloys, presumably owing to a slow rate of methanol dehydrogenation on the Ru-rich surface and insufficient number of Pt sites required for dissociative chemisorption of methanol.

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 effect of chloride and (bi)sulfate anions in the supporting acid electrolyte on the chemistry of underpotential deposition of Cu on Pt(111) and Pt(100) single crystal surfaces was studied using a combination of electrochemical and nonelectrochemical techniques. The presence of these anions above a threshold concentration caused a splitting in the voltammetry peaks for Cu UPD on both Pt(111) and Pt(100), with the second or split-off peak at a lower underpotential. This splitting was attributed to competition between the Cu adatoms and the adsorbed anions and the increase in thermodynamic driving force needed to displace the anions from the Pt substrate in order to form a Cu monolayer. The magnitude of the splitting appeared to be proportional to the relative strengths of the anion-Pt bonding, being larger for chloride than (bi)sulfate on either surface and being larger for the (100) surface than for the (111) surface for either anion. By the use of ex situ AES and LEED, we determined that in nearly "Cl-free" supporting electrolyte Cu appeared to be deposited at underpotential in metallic islands (or "patches") having the Pt lattice constant (pseudomorphic growth). In the presence of Cl- the Cu was deposited at underpotentials into a Cu-Cl adlattice. At the Nernst potential, however, in both "Cl-free" and Cl-containing electrolyte, Cu formed a uniform metallic monolayer having the Pt lattice constant, i.e. a pseudomorphic monolayer.

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 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  - The kinetics of O2 reduction on the Au (110) and the Au (111) single crystal electrodes have been examined using the rotating disc method. The quality of the surfaces has been determined by Auger electron spectroscopy and LEED. Two electrons are exchanged in O2 reduction on both surfaces. HO2 appears completely stable on the (111) face. The half-wave potential for the Au (110) surface is ca. 70 mV more positive than that for the Au (111) face. The cathodic and anodic kinetic data for the O2/HO2 and HO2−/OH− couples support the mechanism with the following initial two steps: O2+e−→O2−(ads) 2 O2−(ads)+H2O→HO2−+O2+OH− Slow further reduction of HO2−, which occurs on the Au (110) face, is controlled by a chemical reaction. The higher activity of the Au (110) face is explained by some reduction of HO2− on a partially discharged OH−, whose adsorption on the Au (111) face is negligible.

AB  - The kinetics of O2 reduction on the Au (100) single crystal electrode have been examined in alkaline electrolytes using the rotating dise method. A comparison has been made with the Au (110) and Au (111) surfaces. The quality of the surfaces has been determined by Auger electron spectroscopy and LEED. A pronounced effect of the crystallographic orientation on the kinetics and mechanism of O2 reduction has been found. The half-wave potential for the Au (100) face is the most positive. O2 reduction, only on this surface, proceeds with the exchange of four electrons in a "series" pathway in the potential region of AuOH formation. The cathodic and anodic kinetic data for the O2/HO2- and HO2-/OH- couples support the mechanism O2+e-→ O2- (ads) 2 O2- (ads)+H2O HO2-+O2+OH- Further reduction of HO2- is controlled by an initial one-electron transfer: HO2-+e-+H2O→ 2 OH-+OH(ads) OH(ads)+e- OH- The OH species adsorbed on the Au (100) face appears considerably discharged. Such a surface apparently interacts more strongly with O2, O2- and HO2-, and is probably the origin of the high activity of the Au (100) face for O2 and HO2- reduction.
