Caption
(Left) Schematic illustration of the formation of a Pt–Co–Mn ternary intermetallic structure, where oxygen vacancies generated at the MnO interface drive atomic ordering within the catalyst.
(Top right) The synthesized nanocatalyst exhibits a uniform atomic-scale structure with an even distribution of Mn, Co, and Pt.
(Bottom right) Owing to these structural characteristics, the catalyst delivers high ORR activity and outstanding durability, outperforming conventional catalysts under practical fuel cell conditions.
