The structure, growth and reactivity of electrodeposited Ru/Au(111) surfaces
(Elsevier, 2001)
In order to elucidate electronic effects on the oxidation of CO on small Ru clusters, we investigated this reaction on well defined Ru/Au(111) model systems via parallel in-situ STM studies of the structure and electrochemical ...
Electrosorption of hydrogen and sulfuric acid anions on single crystal platinum stepped surfaces. Part II. The [110] zone
(Elsevier, 1991)
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 ...
Catalytic effects of monolayers of metals deposited at underpotentials: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was recently shown that the monolayers of some metals deposited at underpotentials
on gold can substantially increase the rates of some redox reactions 1 , and the
rate of oxygen reduction:. This note reports the ...
ALSV investigation of the phase composition of electrolytic Cu + Sn alloys
(Elsevier, 1991)
Anodic linear sweep voltammograms (ALSVs) have been recorded for thin layers of Cu + Sn alloys electrochemically deposited on graphite from a pyrophosphate bath. Three characteristic peaks were found. The first peak, ...
Electrochemically deposited iridium-oxide: Estimation of intrinsic activity and stability in oxygen evolution in acid solution
(Elsevier, 2021)
Hydrated iridium oxyhydroxide (IrOx) films were electrochemically deposited from an alkaline oxalic solution at constant anodic potentials and by applying a potential cycling protocol, in both cases with variation of the ...
Oxidation of d-glucose on single-crystal platinum electrodes: A mechanistic study
(Elsevier, 1992)
Reaction kinetics of glucose oxidation on single-crystal platinum electrodes has a pronounced structure sensitivity. Quasi-steady-state measurements show Tafel slopes of 120 mV per decade for Pt(111), but 60 mV per decade ...
Underpotential deposition of metals in the presence of surfactants: Deposition of thallium and lead on an Ag (100) electrode in the presence of sodium dodecyl sulphate
(Elsevier, 1985)
In this work sodium dodecyl sulphate (SDS) was used to modify the surface of an Ag (100) single crystal electrode. Both the underpotentlal deposition (UPD) and overpotential deposition (OPD) of thallium and lead were studied ...
The electrocatalytic properties of the oxides of noble metals in the electro-oxidation of some organic molecules
(Elsevier, 1997)
The electro-oxidation of organic compounds on gold and silver electrodes can occur either in a potential range more negative than that where the metal oxides are formed or within the more positive range where the surface ...
Structural effects in electrocatalysis: oxidation of formic acid and hydrogen adsorption on platinum single-crystal stepped surfaces
(Elsevier, 1986)
The oxidation of formic acid and hydrogen adsorption have been measured on platinum single-crystal stepped surfaces with five orientations. A pronounced structural sensitivity of both reactions has been found. They show a ...
Oxygen reduction on the Au (311) electrode surface in alkaline electrolyte
(Elsevier, 1988)
Oxygen reduction was studied for the first time using a single crystal electrode in a rotating disc-ring arrangement. The Au (311) surface shows a complex behaviour, with a very high activity in certain potential regions. ...
