Limiting oxygen coverage on platinized platinum; Relevance to determination of real platinum area by hydrogen adsorption
TL;DR: In this paper, a limiting oxygen coverage is found on platinized platinum electrodes and identified as a monolayer of chemisorbed oxygen atoms, and the problems involved in interpreting hydrogen adsorption measurements in terms of real electrode areas are discussed.

A study of the dissolution of platinum, palladium, rhodium and gold electrodes in 1 m sulphuric acid by cyclic voltammetry
D.A.J. Rand,Ronald Woods +1 more
TL;DR: In this paper, it is emphasized that metal dissolution currents should not be ignored when examining electrochemical processes on noble metals at anodic potentials, and evidence in support of an anodic mechanism for noble metal corrosion has been obtained from studies of the variation of dissolution rate with both potential and temperature.
Journal ArticleDOI
The nature of adsorbed oxygen on rhodium, palladium and gold electrodes
D.A.J. Rand,Ronald Woods +1 more
TL;DR: In this paper, a basis for distinguishing between chemisorption and phase formation is presented, which can be used for accurate measurement of real surface area of rhodium and palladium electrodes.
Journal ArticleDOI
Hydrogen adsorption on platinum, iridium and rhodium electrodes at reduced temperatures and the determination of real surface area
TL;DR: In this article, the saturation hydrogen coverage and the real surface area of an electrode were determined directly from the voltammogram of platinum and iridium electrodes in 5 M sulphuric acid at −72°C.

A ring-disk electrode study of the current/potential behaviour of platinum in 1.0 M sulphuric and 0.1 M perchloric acids
TL;DR: The potential range for the formation of Pt(II) corresponds to that predicted on thermodynamic grounds for the reduction of PtO 2, and an unidentified species is produced during the oxidation of the platinum electrode.
