WebFeb 22, 2024 · Highly active PtCo-alloy nanoparticles are composed of Pt 3 Co core with a Pt-rich shell of ∼2 to 3 atomic layers that exhibit higher ORR catalyst activity by moderating the binding strength of reaction intermediates and efficiently breaking the double-bond in O 2 molecule. 6 This moderation in adsorbate binding strength is enabled by the ... WebMay 17, 2024 · In this work, PtCo nanoparticles (NPs) on hierarchically ordered mesoporous carbon (PtCo/OMC) are synthesized for polymer electrolyte membrane fuel cells (PEMFCs) aiming to improve the activity and durability of the Pt-based catalyst towards oxygen reduction reaction (ORR). Specifically, the OMC is prepared through a solvent evaporation …
