Effects of Li+, K+, and Ba2+ Cations on the ORR at Model and High Surface Area Pt and Au Surfaces in Alkaline Solutions
Abstract
This Letter reveals new findings on the influence of noncovalent interactions on the electrochemical interface. Using surface X-ray scattering, we demonstrate that the barium cations are located at 3.4 Å away from the surface, suggesting that they are partially hydrated, though not adsorbed at the surface. The effect of the cation on the oxygen reduction reaction (ORR) ranges from significant (Pt) to little (Au), depending on the nature of the metal and cation. Finally, we show that these results, as obtained on well-defined single-crystal surfaces, correlate well with observations on high surface area nanoparticle catalysts.

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.
