Role of Electronic Property of Pt and Pt Alloys on Electrocatalytic Reduction of Oxygen
Open accessAbstract
Electrocatalytic activity of PtNi alloy surfaces formed by sputtering was investigated toward oxygen reduction reaction (ORR) in perchloric acid solution. Hydrodynamic voltammograms with rotated electrodes were utilized to measure the activity. Maximum activity was observed at ca. 30% of Ni content by which a ten times larger kinetic current density than that of pure Pt was attained. X‐ray photoelectron spectroscopy analysis of the surfaces after the reaction indicated that the active surfaces were completely covered by Pt. The effect of Pt interatomic distance at the surface or of surface roughening was excluded as the cause of high activity. We present a mechanism of the ORR based on d electron vacancy at the surface Pt due to Ni content a few monolayers below the surface. This type of catalyst will contribute in development of fuel cells for electric vehicles and other applications.

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.
