Size-Dependent Activity of Palladium Nanoparticles for Oxygen Electroreduction in Alkaline Solutions
Open accessAbstract
The objective of this study is to investigate the effect of palladium particle size on catalytic activity for oxygen reduction reactions (ORRs) in alkaline solutions. Carbon-supported palladium catalysts with average Pd particle sizes from were obtained by treating a 20% catalyst in a gas at elevated temperatures from , respectively. The specific activity of the catalysts for the ORRs, described by a kinetic ORR current normalized to the Pd active surface area, was found to increase continuously by a factor of about 3 with increased particle size from without reaching a maximum. The mass activity increased by a factor of 1.3 when Pd particle size increased from and then decreased with increased Pd particle size. The hydrogen peroxide yield on the catalysts was negligible, especially in the mixed kinetic-diffusion controlled region, indicating that the four-electron transfer path is dominant for the ORR on the in alkaline solutions.

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.
