Abstract

Porous platinum nanotubes (PtNTs) with a all thickness of 5 nm, an outer diameter of 60 nm, and a length of 5–20 μm are synthesized by galvanic displacement with silver nanowires, which are formed by the ethylene glycol reduction of silver nitrate. Oxygen reduction reaction (ORR) and durability experiments are conducted for PtNTs, Pt nanoparticles supported on carbon (Pt/C), and bulk polycrystalline Pt (BP‐Pt) electrocatalysts to evaluate their catalytic properties for use as cathode catalysts in proton exchange membrane fuel cells. PtNTs demonstrate improved mass and specific activity for ORR and durability to Pt/C. Following durability testing, PtNTs exhibit specific ORR activity approaching that of BP‐Pt. Catalyst activity for the methanol oxidation reaction (MOR) is characterized through cyclic voltammetry and chronoamperometry techniques to evaluate the materials for use as anode catalysts in direct methanol fuel cells. The PtNTs show improved specific activity for MOR and chronoamperometry characteristics over Pt/C and BP‐Pt catalysts.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Carbon support material corrosion can degrade catalyst, causing catalyst NPs to detach from the support and sinter on the membrane, leading to poor fuel cell performance.

    “the carbon support materials corrosive specification can degrade catalyst, as a resulting catalyst NPs detach from the support and sinter on the membrane, leading to poor fuel cell performance.”

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.
