Kinetic and mechanistic study of methanol oxidation on a Pt 100/ surface in alkaline media
(Elsevier, 1998)
A comparative study of methanol oxidation on a Pt(100) surface was carried out in bicarbonate, carbonate and different pH values of sodium hydroxide solutions. It was shown that Pt(100) adsorbs OH and 'poisoning species'. ...
Investigation of the anodic processes on platinum in perchlorate and chlorate solutions by linear sweep voltammetry using the rotating double-ring electrodes
(Elsevier, 1976)
There have been several attempts to elucidate events occurring on platinum immersed into pure perchloric acid solutions, when submitted to high anodic polarisation. The polarisation curve was shown to exhibit two levels, ...
A novel nonenzymatic hydrogen peroxide amperometric sensor based on AgNp@GNR nanocomposites modified screen-printed carbon electrode
(Elsevier, 2020)
A nonenzymatic hydrogen-peroxide sensor was developed by utilization of silver nanoparticles and graphenenanoribbons. The mentioned composite was inflicted on a screen-printed carbon electrode which provides disposable,r ...
Oxide formation on gold single crystal stepped surfaces
(Elsevier, 1988)
Oxide formation and anion adsorption have been studied on gold single crystal stepped surfaces. Most of the measurements were performed in sulphuric and some in perchloric acid solutions by cyclic voltammetry and by double ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
The influence of OH- chemisorption on the catalytic properties of gold single crystal surfaces for oxygen reduction in alkaline solutions
(Elsevier, 1996)
Oxygen reduction on gold single crystal electrodes of various orientations, Au(hkl), in 0.1 M NaOH was studied by rotating disk electrode and rotating disk ring electrode techniques, with a goal to correlate the physical ...
Electrocatalysis by foreign metal monolayers: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was demonstrated that some foreign metal monolayers formed by underpotential deposition have pronounced catalytic effects on the oxidation of formic acid on platinum. The explanation of these effects was sought within ...
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 ...
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 ...
