Oxygen Reduction on Platinum Low-Index Single-Crystal Surfaces in Alkaline Solution: Rotating Ring DiskPt( hkl ) Studies
Abstract
The first results of a study of the oxygen reduction reaction on a rotating ring−disk electrode using single-crystal Pt disk electrodes in alkaline solution are presented. The order of activity of Pt( hkl ) in 0.1M KOH increased in the sequence (100) < (110) < (111) for both oxygen and peroxide reduction. These differences are attributed to the structure sensitivity of hydroxyl anion (OH - ) adsorption on Pt( hkl ) and its inhibiting (site blocking) effect on oxygen kinetics. Two different types of OH ads occur on Pt(100) and Pt(110), a reversible OH rv, and an irreversible OH ir, while only the reversible form is formed on Pt(111). Very small fluxes ( I R / N ≪ 0.01 I D ) of peroxide were detected at the ring at potentials where the surfaces have only the reversible form of OH ads . More peroxide ( I R / N < 0.03 I D ) was found with the Pt(100) and Pt(110)surfaces in the potential region where irreversible adsorption occurs. The mechanism of O 2 reduction was also affected by adsorbed hydrogen with increased formation of peroxide ions in this potential region; correspondingly, adsorbed hydrogen was found to have an inhibiting effect on peroxide reduction, the effect decreasing in the order (111) > (100) ≫ (110).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
