Single-Atom Ce Enables Interfacial Pathway Regulation of Fe2 Atomic Pairs in Alkaline Oxygen Reduction
Fe2 atomic pairs are among the most active motifs in Fe–N–C catalysts for the alkaline oxygen reduction reaction (ORR), but their performance is limited by an activity–stability trade-off. In alkaline media, slow interfacial water dissociation restricts proton-coupled electron transfer (PCET). Under these proton-defi...
