Pt-Co@Pt Octahedral Nanocrystals: Enhancing Their Activity and Durability toward Oxygen Reduction with an Intermetallic Core and an Ultrathin Shell

Minghao Xie et al.

Summary: In this study, Pt-Co@Pt octahedral nanocrystals were successfully synthesized with an intermetallic Pt-Co core and an ultrathin Pt shell dominated by {111} facets on the surface. These nanocrystals showed significantly improved catalytic performance towards the oxygen reduction reaction compared to a commercial Pt/C catalyst, with a mass activity 13.4 times higher and a specific activity 29.5 times higher. Importantly, the mass activity of the nanocrystals only decreased by 21% after 30,000 cycles of accelerated durability testing, indicating their outstanding potential as catalysts for ORR and related reactions.
