Electrocatalytic Reduction of Oxygen by FePt Alloy Nanoparticles
Abstract
Fe x Pt 100- x nanoparticles of different compositions ( x = 63, 58, 54, 42, 15, and 0) were prepared and loaded onto a glassy carbon (GC) electrode where their catalytic activities in the electroreduction of oxygen were examined and compared. Cyclic and rotating disk voltammetric studies of the resulting Fe x Pt 100- x /GC electrodes showed that the catalytic activity for oxygen reduction exhibited a peak-shape dependence on the particle composition ( x ). Among the series of nanocatalysts under study, Fe 42 Pt 58 particles showed the maximum activity for O 2 reduction in terms of the reduction overpotential and current density. This was accounted for by the effects of the Fe content on the electronic structures of the Pt active sites and the resulting Pt−O interactions. Kinetic analyses showed that direct four-electron reduction of adsorbed oxygen occurred on these catalyst surfaces. Additionally, the rate constant of O 2 reduction increased with increasing Pt content in the alloy particles; yet, at x ≤ 42, the rate constant exhibited only a very small increment. These studies suggest that the Fe 42 Pt 58 particles might represent an optimal composition for oxygen reduction among the series of nanoparticle catalysts under the present study.

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.
