Catalyst Poisoning Property of Sulfonimide Acid Ionomer on Pt (111) Surface
Open accessAbstract
The catalyst poisoning property of a novel ionomer, NBC4, which has two sulfonimide acid groups in its side chain ended with a perfluorobutane, instead of sulfonic acid groups as Nafion does, was theoretically and experimentally compared with that of Nafion. A density functional theory combined with a continuum electrolyte theory showed that the adsorption is weaker for sulfonimide anion than for sulfonate anion on Pt (111) surface. Electrochemical measurements using Pt (111) surfaced single crystal electrodes covered with the ionomer films showed the weaker anion adsorption and higher ORR activity by ca. 50% at 0.82 V vs the reversible hydrogen electrode for NBC4 than for Nafion.

The interfacial structure depends on the surface properties of the catalyst (such as the concentration of Pt and the crystallinity of the carbon support), thus changing the physical properties of the ionomer, which in turn affects the water absorption, proton conductivity, and gas permeability at the interface.

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.
