“…In order to avoid any potential induced changes of the catalyst, the potential window was kept in between 0.00 and 1.05 V RHE . Both NP Ag and PC Ag exhibit no specific features in this region, so mainly capacitive currents were observed in agreement with previous findings [18][19][20]. Hydrogen evolution occurs at more negative potentials than -0.3 V RHE , whereas at potentials more positive than 1.05 V RHE , large oxide features can be observed.…”

In this study the oxygen reduction reaction (ORR) is investigated on a nanoparticulate silver electrocatalyst in alkaline solution. The catalytic activity of the catalyst is determined both in terms of mass activity as well as specific activity and turn over frequency, respectively. It is demonstrated that the established mass activities are independent of the applied catalyst loading, an essential requirement for a reasonable analysis. The determination of the electrochemically active surface area (ECA) or the number of electrochemically accessible sites (NECAS), respectively, is performed by the underpotential deposition of lead. The obtained value of the activity is compared to activities of polycrystalline silver and platinum measured in the same electrolyte, as well as to literature data.

“…The electrochemical behavior shown in Fig. 2 for the bare silver surfaces is in good agreement with the results for Ag(1 1 1) single-crystal electrodes in 0.1 M NaOH reported by Savinova et al [45] and for Ag(1 0 0) by Jovic et al [46]. These authors assume that the current peak at about )0.8 and )0.6 V vs. SCE for Ag(1 0 0) and Ag (1 1 1), respectively, is connected with the adsorption of OH À ions.…”

“…It should be noted that Ag(I) hydroxide is unstable at room temperature and decomposes to Ag 2 O and water [27,93]. Although formation of [41,42,71,79,[94][95][96][97], the existence of silver-hydroxyl ion species under UHV conditions seems to be highly unlikely.…”

Electrochemical properties of oxide-covered polycrystalline Ag electrodes were studied in a 0.1 M KOH aqueous electrolyte. The oxide layers formed by a constant potential oxidation at 420 mV vs. Hg|HgO are composed of oxygen-deficient Ag 2 O as follows from the XPS and Auger experiments. Steady-state conditions required for collection of valid impedance spectra were obtained at a potential range of 345-365 mV. The components of the equivalent circuit used for the impedance spectra analysis are analysed as a function of the Ag 2 O layer thickness. The value of the coefficient of the constant phase element (CPE) attributed to the oxide layer is Ag 2 O thickness dependent. On the other hand, the components of the CPE describing the double-layer capacitance of the oxide-covered Ag electrode are independent on the oxide thickness and their values are comparable to those obtained for the oxide-free metal. This indicates that the double-layer capacitances of oxide-covered and oxide-free Ag electrodes are similar.
