Palladium–Tin Alloyed Catalysts for the Ethanol Oxidation Reaction in an Alkaline Medium
Abstract
In this paper, we present a study of a series of carbon-supported Pd–Sn binary alloyed catalysts prepared through a modified Polyol method as anode electrocatalysts for direct ethanol fuel cell reactions in an alkaline medium. Transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and aberration-corrected scanning transmission electron microscopy equipped with electron energy loss spectroscopy were used to characterize the Pd–Sn/C catalysts, where homogeneous Pd–Sn alloys were determined to be present with the surface Sn being partially oxidized. Among various Pd–Sn catalysts, Pd 86 Sn 14 /C catalysts showed much enhanced current densities in cyclic voltammetric and chronoamperometric measurements, compared to commercial Pd/C (Johnson Matthey). The overall rate law of ethanol oxidation reaction for both Pd 86 Sn 14 /C and commercial Pd/C were also determined, which clearly showed that Pd 86 Sn 14 /C was more favorable in high ethanol concentration and/or high pH environment. Density functional theory calculations also confirmed Pd–Sn alloy structures would result in lower reaction energies for the dehydrogenation of ethanol, compared to the pure Pd crystal.

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.
