Article Synopsis
- * These nanoparticles preferentially oxidize carbon monoxide, thus reducing platinum poisoning and improving fuel cell stability.
- * The study investigates potential impurities in the Ru nanoparticles from the synthesis process using advanced techniques like atom probe tomography (APT) and scanning transmission electron microscopy (S)TEM for detailed chemical analysis at the nanoscale.
Ru@Pt core-shell nanoparticles are currently being explored as carbon monoxide tolerant anode catalysts for proton exchange membrane fuel cells. However, little is known about their degradation under fuel cell conditions. In the present work, two types of Ru@Pt nanoparticles with nominal shell thicknesses of 1 (Ru@1Pt) and 2 (Ru@2Pt) Pt monolayers are studied as synthesized and after accelerated stress tests.
