XPS investigations of the electrochemical double layer on silver in alkaline chloride solutions

Electrochemical Behavior of Sintered CuAg4 at. pct Alloy

“…To recognize these reactions, the voltammogram obtained on sintered alloy is compared with the voltammograms obtained on pure copper and silver ( Figure 5). The current peak A 1 is attributed to the adsorption of OH − and formation of the first oxide monolayer based on literal [10][11][12][13][14][15][16][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] data to which, with different in situ techniques, the presence of absorbed hydroxyl ions on the surface of copper and silver in alkaline electrolytes is proved in the quoted area of potential. It is obvious that the current waves marked as A 2 and A 3 correspond to copper oxides formation.…”

“…Pure silver is also investigated widely from the electrochemical point of view. [27][28][29][30][31][32][33][34][35][36][37][38][39][40] The presence of adsorbed hydroxyl ions on both copper and silver electrode surface in alkaline solutions, even in so-called doublelayer region, was proved by in situ scanning electron microscopy [10,12] and other surface analytical methods. Thus, the adsorption of hydroxyl ions is considered to be the first reaction step that can take place during the anodic polarization of CuAg4 at.…”

Silver deposition on titanium surface by electrochemical anodizing process reduces bacterial adhesion of Streptococcus sanguinis and Lactobacillus salivarius

“…In general, it is described that bacterial colonization is enhanced on rough surfaces because of surface features, such as valleys, depressions, pits and edges (Hecht & Strehblow ; Wu et al. ; Rodríguez‐Hernández et al.…”

Tailoring the morphology and electrocatalytic properties of electrochemically formed Ag/TiO2 composite deposits on titanium surfaces

“…40,41 Much more cathodic, between −0.5 and −0.8 V vs. SCE, at a substantially expanded current scale, a pair of peaks, which were attributed to the adsorption/desorption of OH − ions 42 can be discerned. The presence of adsorbed OH − ions was recently confirmed by XPS, 43,44 Raman spectroscopy 45 and by electron diffraction. 46 To estimate the fraction of silver within the Ag/TiO 2 composite layer, which may be transformed into oxides, a titanium electrode covered by a Ag/TiO 2 layer in perchlorate solution was rinsed with distilled water, transferred into a 0.1 M NaOH solution, and then voltammograms were recorded in the potential range −1.0 to 0.9 V. These voltammograms are presented in Figs.…”
