AB  - Water electrolysis powered by renewables is regarded as the feasible route for the production of hydrogen, obtained at the cathode side through electrochemical hydrogen evolution reaction (HER). Herein, we present a rational strategy to improve the overall HER catalytic performance of Pt, which is known as the best monometallic catalyst for this reaction, by supporting it on a conductive titanium oxynitride (TiONx) dispersed over reduced graphene oxide nanoribbons. Characterization of the Pt/TiONx composite revealed the presence of small Pt particles with diameters between 2 and 3 nm, which are well dispersed over the TiONx support. The Pt/TiONx nanocomposite exhibited improved HER activity and stability with respect to the Pt/C benchmark in an acid electrolyte, which was ascribed to the strong metal–support interaction (SMSI) triggered between the TiONx support and grafted Pt nanoparticles. SMSI between TiONx and Pt was evidenced by X-ray photoelectron spectroscopy (XPS) through a shift of the binding energies of the characteristic Pt 4f photoelectron lines with respect to Pt/C. Density functional theory (DFT) calculations confirmed the strong interaction between Pt nanoparticles and the TiONx support. This strong interaction improves the stability of Pt nanoparticles and weakens the binding of chemisorbed H atoms thereon. Both of these effects may result in enhanced HER activity.

AB  - Hydrogen evolution reaction (HER) was studied in alkaline solution on Pt(poly) electrode modified by spontaneously deposited Ir nanoislands. Comprehensive insight into the characteristics of the bimetallic Ir/Pt(poly) catalysts was obtained by a combination of Atomic Force Microscopy (AFM), Field Emission Scanning Electron Microscopy (FESEM), X-ray Photoelectron Spectroscopy (XPS) and classical electrochemical techniques. HER investigations have shown that the presence of spontaneously deposited Ir enhances the activity of bare Pt(poly) in alkaline solution. This was attributed to the heterogeneity of the active surface sites and to the electronic interaction between two metals in close contact which together facilitated the adsorption of the H intermediate species.

AB  - Hydrogen evolution reaction (HER) was studied on polycrystalline Pd, Pd(poly), decorated by spontaneously deposited Ru nanoislands below full coverage. Surface features of as-prepared bimetallic Ru/Pd(poly) electrodes were explored by Field Emission Scanning Electron Microscopy with Energy Dispersive X-ray Spectrometer. Electrochemical properties and hydrogen evolution activities of obtained electrodes were investigated in an alkaline electrolyte by Cyclic and Linear Sweep Voltammetry, respectively. It was found that the activities of bimetallic Ru/Pd(poly) electrodes for HER significantly exceeded the activity of bare Pd(poly) and approached the activity of Pt, which is the most active material for this reaction. This enhancement was explained by the favorable influence of the electronic interaction between Pd substrate and Ru nanoislands on the adsorption of the reactive H species.

AB  - Hydrogen evolution reaction (HER) was explored on tri-metallic Rh"Pd/Au(poly) and bimetallic Pd/Au(poly) and Rh/Au(poly) electrodes in alkaline solution. Electrodes were prepared by the spontaneous deposition of either Pd or Rh and by co-deposition of both Rh and Pd on polycrystalline gold electrode. Characterization of modified electrodes was performed by cyclic voltammetry in alkaline solution, while additional information about phase analysis, chemical composition and surface morphology of tai-metallic Rh"Pd/Au(poly) electrode were acquired using X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy and atomic force microscopy. Investigations of HER catalysis have shown that the activity of tri-metallic Rh Pd/Au(poly) electrode exceeds the activities of both Pd/Au(poly) and Rh/Au(poly) electrodes, meaning that the synergism between co-deposited Pd and Rh islands is achieved. Moreover, Rh"Pd/Au(poly) electrode showed significant approach to the activities of bulk Pd and Rh electrodes for HER, especially when taking into account low activity of bare Au substrate. Synergistic effect of co-deposited Pd and Rh islands is a consequence of the strong electronic interaction between three metals in a close contact, which promotes the activity for HER by lowering the adsorption energy of Hads intermediate.

AB  - Hydrogen evolution reaction (HER) was investigated in alkaline solution on tri-metallic Rh"Pd/Pt(poly) electrode, prepared by spontaneous deposition of Rh on top of Pd/Pt(poly) electrode with intermediate Pd coverage of 35%. Characterization of tri-metallic catalyst was performed by electrochemical methods of cyclic voltammetry and CO stripping voltammetry, while its activity for HER was tested by linear sweep voltammetry in 0.1 M NaOH. Rh"Pd/Pt(poly) catalyst has shown superior catalytic activity for HER with respect to initial Pt(poly) and both corresponding bimetallic Pd/Pt(poly) and Rh/Pt(poly) electrodes. This was explained by a strong synergistic electronic interaction between three metals in close contact induced at a number of different active sites across the surface of tri-metallic catalyst, which results with lowering of the binding energy for the adsorption of H intermediate species.

AB  - Rh/Au(100) and Rh/Au(111) electrodes with Rh coverage below a monolayer are prepared by a spontaneous deposition method. Electrodes are characterized by AFM and XPS. Hydrogen evolution reaction (HER) is studied by linear sweep voltammetry in 0.1 M HClO4 solution. Results for gold single crystals with 50% Rh coverage, which have shown the best catalytic activity for HER are presented in this work. Enhanced catalytic activity of such bimetallic electrodes compared to the ones with higher Rh coverage is ascribed to the presence of smaller Rh islands, which provide suitable active surface sites. Rather strong electronic interaction between Rh deposit and gold substrates, which is manifested by the upshift of Rh3d5/2 photoelectron line, also contributes to their activity. Structural effect is manifested through a higher activity of 50% Rh/Au(111) than 50% Rh/Au(100), which is consistent with the difference in activity of respective bare gold single crystals.

Characterization of obtained Rh/Pd(poly) nanostructures was performed ex situ by AFM imaging and by X-ray photoelectron spectroscopy. In situ characterization of the obtained electrodes and subsequent ethanol oxidation measurements were performed by cyclic voltammetry in 0.1 M KOH. Palladium surface with 50% Rh coverage exhibited the highest catalytic activity for ethanol oxidation in alkaline media. The origin of the enhanced catalysis of Rh/Pd(poly) surfaces with respect to bare Pd was explained by the electronic effect. Possible reaction pathways for ethanol oxidation were discussed taking into account the activity of obtained bimetallic electrodes for the oxidation of CO and acetaldehyde, as the most probable reaction intermediates.

AB  - Catalytic properties of polycrystalline gold, Au(poly), were examined for the oxygen reduction reaction in alkaline solution using the rotating disc electrode technique. On electrochemically prepared Au(poly), oxygen reduction proceeds partly through 4e-reaction pathway resembling the activity of bare Au(100) in alkaline solution. Electrochemical behavior of such Au(100)-like polycrystalline gold electrode was compared with bare Au(100) surface, as well as with stepped Au(210)=Au[2(100)x(110)] and Au(533)=Au[4(111)x(100)] surfaces. It is shown that polycrystalline gold electrode behaved in a similar manner as stepped Au[n(111)x(100)] surfaces, meaning that the enrichment in (111)x(100) steps, rather than in (100) orientation is responsible for a partial 4e-reaction pathway in alkaline solution.

AB  - Rhodium nanoislands were spontaneously deposited on Au(111) up to a full coverage. Obtained Rh/Au(111) bimetallic surface was characterized ex situ by Atomic Force Microscopy imaging and by X-Ray Photoelectron Microscopy, while in situ characterization was performed by Cyclic Voltammetry in 0.1 M NaOH solution. Pronounced catalysis of hydrogen evolution reaction has been observed on Rh modified Au(111) surface compared to bare Au(111). This is ascribed to the suitable geometry of obtained Rh/Au(111) nanostructured electrode surface providing large number of active sites and to the electronic interaction between Au(111) substrate and Rh deposit.

AB  - Hydrogen evolution reaction (HER) was investigated on bimetallic Rh/Pd(poly) electrodes in alkaline solution. Bimetallic electrodes were obtained by a spontaneous deposition of rhodium on polycrystalline Pd. Characterization of obtained electrodes was performed ex situ by atomic force microscopy and by spectroscopic ellipsometry. The results have shown that the coverage of palladium substrate with the deposited Rh nanoislands was up to 50%, depending on the chosen deposition time. Electrochemical properties and catalytic activity of Rh/Pd(poly) nanostructures for HER were examined in 0.1 M NaOH solution by cyclic voltammetry and linear sweep voltammetry. Rh/Pd(poly) electrodes have shown an enhanced activity for HER with respect to bare Pd(poly), which was ascribed to the strong electronic interaction between palladium substrate and the deposited rhodium islands. The enhanced catalytic activity of 50% Rh/Pd(poly) for HER in alkaline solution is comparable to that of bare Pt(poly).

Both Pd/Pt(poly) and Rh/Pt(poly) surfaces exhibited an enhanced catalysis for HER with respect to bare Pt(poly), which is explained by a strong synergistic electronic effect of platinum substrate on the deposited Pd or Rh nanoislands.

AB  - Hydrogen evolution reaction (HER) was studied on Pd/Au(1 1 1) bimetallic surfaces in alkaline solution. Au(1 1 1) was modified by palladium nanoislands spontaneously deposited using PdSO4 center dot 2H(2)O and PdCl2 salts. As revealed from both surface topography Atomic Force Microscopy (AFM) and phase AFM images, for the same deposition conditions, the obtained Pd/Au(1 1 1) nanostructures differ depending on the counter anion in the depositing palladium salt. These differences are reflected on their catalytic activity toward HER, which occurs between the potentials for pure consisting metals. HER proceeded with the same mechanism, but it is shifted to more positive potentials for Pd/Au(1 1 1) nanostructures obtained using PdCl2 salt with respect to ones obtained using PdSO4 salt. Better catalytic activity of Pd/Au(1 1 1) nanostructures obtained using PdCl2 salt can be explained by their surface structure consisting of smaller and thinner Pd nanoislands, preferentially deposited at steps, which provides more Pd and Pd/Au sites suitable for hydrogen evolution reaction.

AB  - Catalytic properties of Pd/Au(111) nanostructures obtained by spontaneous palladium deposition using PdSO4 and PdCl2 salts were examined for the oxidation of ethanol in alkaline media. Atomic force microscopy has shown that counter anions in Pd salts are responsible for the differences in surface topography. In both cases the oxidation of ethanol is characterized by the rise of a new peak at approximately the same potential for the same coverage, indicating similar electronic modification of Pd islands by the Au(111) substrate. Pd/Au(111) nanostructures obtained using PdCl2 salt have shown higher ethanol oxidation current densities, which can be ascribed to the surface structure consisting of thinner and smoother Pd deposit providing more convenient sites for the adsorption of ethanol and its subsequent oxidation.

AB  - The effect of spontaneously deposited rhodium nanoislands on the electrocatalytic activity of polycrystalline gold, Au(poly), for oxygen reduction reaction (ORR) was studied using rotating disc electrode technique in 0.1 M HClO4 solution. Surface topography atomic force microscopy (AFM) images of obtained Rh/Au(poly) surfaces revealed that both the size and coverage of rhodium nanoislands increase with the deposition time, for a given depositing conditions. The exact values of rhodium coverage ranging from 50% to the full coverage, and the qualitative changes in the surface chemical composition with respect to bare gold were estimated from phase AFM images. Deposited Rh was also identified by the changes in cyclic voltammetry (CV) profiles from which potential limits for ORR were determined. Obtained Rh/Au(poly) surfaces have shown a significant shift of the initial potential for ORR to the more positive potentials with respect to pure gold already for 50% Rh coverage, indicating that a pronounced electronic effect is responsible for the lowering of the activation energy for oxygen adsorption. The initial potential increases only slightly with the further increase of Rh coverage. Reaction pathway changes from 2e- reduction at lower overpotentials to a partial 4e- reduction at higher overpotentials. The later is attributed to the increased activity of obtained Rh/Au(poly) surfaces towards hydrogen peroxide reduction (HPRR), which appear as an intermediate during ORR. The fraction of 4e- reduction slightly increases with the increase of Rh coverage.

AB  - Oxygen reduction reaction (ORR) was studied on polycrystalline gold, Au(poly), modified by nanosized palladium islands in 0.1 M HClO4 solution using rotating disc electrode technique. Paladium was spontaneously deposited from 1 mM PdSO4 center dot 2H(2)O + 0.5 M H2SO4 solution for various deposition times at a submonolayer coverage. Topography of obtained Pd/Au(poly) surfaces was observed by tapping mode atomic force microscopy (AFM), while chemical surface composition changes were detected by simultaneously performed phase AFM. Deposited Pd islands were nonuniform in size and randomly distributed over the gold substrate. Size and number of Pd islands increase with the increase of the deposition time, and consequently surface coverage increases too. Deposited Pd was also identified by the changes in cyclic voltammetry (CV) profiles from which an active surface area was estimated. Obtained Pd/Au(poly) surfaces have shown a significant catalytic activity towards oxygen reduction reaction which increases with the increase of Pd islands coverage. The initial potential of ORR was shifted positively, while reaction pathway changes from 2e-reduction on pure gold to 4e-reduction on Pd modified gold. Additionally, obtained Pd/Au(poly) surfaces have shown a significant activity towards hydrogen peroxide reduction (HPRR), which appear as an intermediate during ORR. This supports the assumption that ORR on Pd/Au(poly) occurs partly through 4e-series reduction pathway, the fraction of which increases with the increase of Pd coverage.

AB  - Hydrogen evolution reaction was studied on Au(111) modified by palladium spontaneously deposited on the Au(111) surface from (1 mM PdSO4 center dot 2 H2O + 0.5 M H2SO4) solution at a submonolayer coverage. Number and size of Pd islands increased with the increase of the deposition time as observed by ex situ surface topography atomic force microscopy (AFM). The overall coverage of the underlying Au(111) surface by the deposited Pd islands was estimated from simultaneously acquired phase AFM images, which provided a clear contrast between different materials. The obtained Pd/Au(111) surfaces have shown a significant catalytic activity toward hydrogen evolution reaction in 0.5 M H2SO4 solution. This is discussed with respect to Pd islands size and coverage and to the influence of an electronic effect induced in Pd islands by the underlying Au(111) substrate.

AB  - The oxygen reduction reaction (ORR) was studied on the polycrystalline Pt electrode in 0.1 M NaCl electrolyte containing various amounts of acetonitrile (AcN). The state of the electrode surface was characterized by the cyclic voltammetry in oxygen free electrolytes, while ORR studies were performed on the polycrystalline Pt rotating disc electrode by the linear sweep voltammetry in oxygen saturated electrolytes. The acetonitrile is chemisorbed on Pt over a wide potential range, inhibiting both hydrogen adsorption and oxide formation. The extent of AcN chemisorption depends on its concentration in the solution. Initial potential of oxygen reduction is shifted negatively, while the ORR current is increasingly reduced with the increase of AcN concentration. Complete inhibition of ORR in the potential range of AcN and Cl-anion coadsorption is achieved for (0.1 M NaCl + 1 M AcN) solution.
