AB  - Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies were obtained depending on the annealing temperature: hexagonal layeredα-Na0.7MnO2.05 nanoplates were obtained at 850 ◦C, while 3-D tunnel structured Na0⋅4MnO2 and Na0⋅44MnO2, both with rod-like morphology, were obtained at 800 ◦C and 900 ◦C, respectively. The investigations of the electrochemical behavior of obtained cathodic materials in aqueous NaNO3 solution have shown that Na0⋅44MnO2 obtained at 900 ◦C has shown the best battery performance. Its initial discharge capacities are 123.5 mA h/g, 113.2 mA h/g, and 102.0 mA h/g at the high current densities of 1000, 2000 and 5000 mA/g, respectively.

AB  - Hydrogen evolution reaction (HER) was investigated on reduced graphene oxide (rGO)-supported Au and PdAu nanoparticles in acid solution. The graphene spread over glassy carbon (rGO/GC) was used as a support for the spontaneous deposition of Au and Pd. The resulting Au/rGO and PdAu/rGO electrodes were characterized using atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) techniques. Phase AFM images have shown that the edges of the rGO sheets were active sites for the deposition of both Au and Pd. XPS analysis revealed that the atomic percentages of both Au and PdAu nanoparticles were slightly higher than 1%. The activity of the PdAu/rGO electrode for the HER was remarkably high, with the overpotential close to zero. HER activity was stable over a 3 h testing time, with a low Tafel slope of approx. −46 mV/dec achieved after prolonged hydrogen evolution at a constant potential.

AB  - HER was examined on various glassy carbon-supported Au and PdAu electrodes in acid solution. The Au/GC electrodes were obtained after Au was electrodeposited on a GC substrate by holding the potential for various times in 0.5 M H2SO4 solution containing AuCl4− ions. PdAu/GC electrodes were obtained after Pd has been added by a spontaneous deposition on previously prepared Au/GC electrodes. Surface morphology and chemical analysis of Au/GC and PdAu/GC electrodes were performed by atomic force microscopy and X-ray photoemission spectroscopy. Electrochemical characterization was performed by cyclic voltammetry in 0.5 M H2SO4 solution, while the linear sweep voltammetry was used to gain insight into the electrocatalytic activity of these electrodes for HER. 30minPd/10minAu/GC electrode consisting of 48% Pd and 65% Au, with the total coverage of the GC substrate with PdAu islands of 70%, showed the best catalytic activity for HER. A remarkable high activity and stability of this electrode makes it a promising catalyst for HER in acid solution. © 2021 Hydrogen Energy Publications LLC

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. © 2019 The Authors.

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 tri-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. © 2018 Hydrogen Energy Publications LLC

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  - Polycrystalline Pd electrode, Pd(poly), is modified by Ru nanoislands using spontaneous deposition method. Coverage of Pd(poly) electrode with the deposited Ru are approx. 20, 30 and 50% as estimated from phase atomic force microscopy images. The oxidation state of Pd substrate and the deposited Ru is determined by X-ray spectroscopy (XPS). Electrocatalytic activity of obtained Ru/Pd(poly) bimetallic electrodes is tested towards methanol oxidation in alkaline medium. Cyclic voltammetry and chronoamperometry experiments show the enhanced activity of Ru/Pd(poly) electrodes towards methanol electrooxidation with respect to bare Pd(poly). This is explained by the presence of Ru islands, which provided RuOH and Pd-RuOH sites, necessary for the oxidation of CO as the main intermediate during the oxidation of methanol at lower potentials. 30% Ru/Pd(poly) is the most active of all examined electrodes.

AB  - Iridium nanoislands are spontaneously deposited on Au(111) from (1 mMIrCl(3) center dot xH(2)O + 0.5 MH2SO4) depositing solution. Atomic Force Microscopy images of the obtained Ir/Au(111) bimetallic surfaces show that gold surface is fully covered with nanosized Ir islands after only 3 min of deposition. X-Ray Photoelectron Spectroscopy analysis shows that the deposit consists of a mixture of adsorbed hydrated IrCl3 and to a lesser extent of Ir(OH)(3). Cyclic Voltammetry characterization in 0.5 M H2SO4 solution does not show clear Hupd region prior to hydrogen evolution reaction (HER). Linear Sweep Voltammetry measurements show pronounced catalysis of HER on Ir modified Au(111) surface compared to bare Au(111).

AB  - The objective of this study was to investigate the modification of materials used in wastewater treatment for possible antimicrobial application(s). Granulated activated carbon (GAC) and natural clinoptilolite (CLI) were activated using Cu2+-and Zn2+-ions and the disinfection ability of the resulting materials was tested. Studies of the sorption and desorption kinetics were performed in order to determine and clarify the antimicrobial activity of the metal-activated sorbents. The exact sorption capacities of the selected sorbents, GAC and CLI, activated through use of Cu2+-ions, were 15.90 and 3.60 mg/g, respectively, while for the materials activated by Zn2+-ions, the corresponding capacities were 14.00 and 4.72 mg/g,. The desorption rates were 2 and 3 orders of magnitude lower than their sorption efficacy for the Cu2+-, and Zn2+-activated sorbents, respectively. The intermediate sorption capacity and low desorption rate indicated that the overall antimicrobial activity of the metal-modified sorbents was a result of metal ions immobilized onto surface sites. The effect of antimicrobial activity of free ions desorbed from the metal-activated surface may thus be disregarded. The antimicrobial activities of Cu/GAC, Zn/GAC, Cu/CLI and Zn/ CLI were also tested against Escherichia coli, Staphylococcus aureus, and Candida albicans. After 15 min exposure, the highest levels of cell inactivation were obtained through the Cu/CLI and the Cu/GAC against E. coli, 100.0 and 98.24%, respectively. However, for S. aureus and yeast cell inactivation, all Cu2+-and Zn2+-activated sorbents proved to be unsatisfactory. A characterization of the sorbents was performed by Xray diffraction (XRD), X-ray photo electron spectroscopy (XPS), and field emission scanning electron microscopy (FE-SEM). A concentration of the adsorbed and released ions was determined by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and mass spectrometry (ICP-MS). The results showed that the antimicrobial performance of the activated sorbents depended on the surface characteristics of the material, which itself designates the distribution and the bioavailability of the activating agent.

AB  - Nanostructured nickel thin films were deposited on glass using glancing angle deposition (GLAD) technique. Cross-sectional field emission scanning electron microscopy images have shown that obtained Ni thin films consist of vertical, tilted or zigzag nano-scaled columns, while X-ray diffraction have shown that (111) orientation prevailed. X-ray photoelectron spectroscopy revealed that apart from metallic nickel, NiO and Ni(OH)(2) were also present in lower amount. Cyclic voltammetry in alkaline solution has shown that hydrogen evolution reaction (HER) was significantly catalyzed on all columnar nanostructures compared to Ni(poly). This was ascribed to the high electroactive surface area (EASA) of porous nickel columns. EASAs for vertical, tilted and zigzag Ni thin layers were higher 32, 25.3, and 24.9 times, respectively, than their geommetric areas. Accordingly, Ni thin films with vertical columns have shown the highest activity for HER.

AB  - Catalytic properties of electrochemically activated polycrystalline gold, Au(poly), modified by spontaneously deposited palladium nanoislands with the coverage below a monolayer were examined for the oxygen reduction reaction (ORR) in alkaline solution using the rotating disc electrode (RDE) technique. Atomic force microscopy (AFM) images have shown that the coverage of randomly distributed nanosized Pd islands ranged from 18% to 77%. Cyclic voltammetry characterization involved hydrogen adsorption/desorption on the deposited Pd islands, as well as their oxidation/reduction at more positive potentials. RDE measurements have shown that, although ORR on Au(poly) proceeds partly through 4e-reduction pathway, in the presence of Pd islands it turns completely to 4e-pathway, exceeding the activity of bare Pd(poly). Among different Pd/Au(poly) nanostructures, the ones with Pd coverage of 18% and 30% have shown the highest activity for ORR in alkaline solution. (C) 2017 Elsevier B.V. All rights reserved.

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.

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.

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.

AB  - This study is focused on the surface modifications of the materials that are used for antimicrobial water treatment. Sorbents of different origin were activated by Ag+-ions. The selection of the most appropriate materials and the most effective activation agents was done according to the results of the sorption and desorption kinetic studies. Sorption capacities of selected sorbents: granulated activated carbon (GAC), zeolite (Z), and titanium dioxide (T), activated by Ag+-ions were following: 42.06, 13.51 and 17.53 mg/g, respectively. The antimicrobial activity of Ag/Z, Ag/GAC and Ag/T sorbents were tested against Gram-negative bacteria E. coli, Gram-positive bacteria S. aureus and yeast C. albicans. After 15 min of exposure period, the highest cell removal was obtained using Ag/Z against S. aureus and E. coli, 98.8 and 93.5%, respectively. Yeast cell inactivation was unsatisfactory for all three activated sorbents. The antimicrobial pathway of the activated sorbents has been examined by two separate tests - Ag+-ions desorbed from the activated surface to the aqueous phase and microbial cell removal caused by the Ag+-ions from the solid phase (activated surface sites). The results indicated that disinfection process significantly depended on the microbial-activated sites interactions on the modified surface. The chemical state of the activating agent had crucial impact to the inhibition rate. The characterization of the native and modified sorbents was performed by X-ray diffraction technique, X-ray photoelectron spectroscopy and scanning electron microscope. The concentration of adsorbed and released ions was determined by inductively coupled plasma optical emission spectroscopy and mass spectrometry. The antimicrobial efficiency of activated sorbents was related not only to the concentration of the activating agent, but moreover on the surface characteristics of the material, which affects the distribution and the accessibility of the activating agent.

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). (C) 2015 Elsevier B.V. All rights reserved.

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). (C) 2015 Elsevier B.V. All rights reserved.",

AB  - Oxygen reduction reaction (ORR) was investigated on polycrystalline palladium, Pd(poly), in acid and alkaline solutions using rotating-disc electrode technique. Pd(poly) was prepared in non-aqueous media which provided surface with good quality and reproducibility. According to cyclic voltammetry curves and to the analysis of polarization curves for ORR and of ones obtained separately for hydrogen peroxide reduction/oxidation reactions, ORR in both media proceeds mainly through 4e-series pathway in the potential regions where Pd surface is either oxide free or oxidized to PdOH. ORR occurs partly through 2e-reduction in the potential region where PdO is present on the surface. As revealed by cyclic voltammetry, spectroscopic ellipsometry and by atomic force microscopy, Pd(poly) surface undergoes both topography and chemical changes during ORR. Pd surface roughness as well as the degree of its oxidation increase during ORR. (C) 2015 Elsevier Ltd. All rights reserved.

AB  - Pd/Pt(poly) and Rh/Pt(poly) bimetallic electrodes prepared by spontaneous deposition of Pd and Rh nanoislands on Pt(poly) at submonolayer coverage were explored as catalysts for hydrogen evolution reaction (HER) in alkaline media. Characterization of bimetallic surfaces was performed ex situ by height and phase AFM imaging and in situ by cyclic voltammetry. HER was investigated by linear sweep voltammetry in 0.1 M NaOH. 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. This electronic effect leads to the lowering of a binding energy of adsorbed hydrogen intermediate and consequently to the lowering of the overpotential for HER. (C) 2013 Elsevier Ltd.

AB  - The effect of ultraviolet (UV) ozone treatment on the surface properties of gold implanted high density polyethylene (HDPE) was investigated at a nanoscale using Atomic Force Microscopy (AFM). HDPE samples were modified by the implantation of gold ions at a dose of 5 x 10(15) ions/cm(2), using energies of 50, 100, 150, and 200 keV, and subsequently treated with UV/ozone. AFM surface topography images revealed that after UV/ozone treatment, the surface roughness of all Au/HDPE samples increased, while Power Spectral Density function increased only for samples implanted using higher energies, with a maximum for 150 keV. The chemical surface composition was homogenous in all cases, which was evidenced by appearance of single peaks in the histograms obtained from the phase AFM images. For UV/ozone treated samples, the shift of the peaks positions in the histograms to the higher values of the phase lag with respect to untreated ones indicated the decrease of surface hardness. Besides, a significant change of fractal dimension of surface grains is observed after UV/ozone treatment. (C) 2014 Elsevier B.V. All rights reserved.

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.
