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-defici...
