Abstract in brief

  • The study explores a dual-metal FeMnNC catalyst with atomically dispersed Fe and MnN, revealing that oxygen reduction primarily occurs on Fe sites with an intermediate spin state, influenced by nearby MnN moieties that enhance activity through spin state transition and electronic modulation.
  • The FeMnNC catalyst exhibits high ORR performance in both alkaline and acidic environments, with half-wave potentials of 0.928 V (in KOH) and 0.804 V (in HClO4), comparable to commercial platinum catalysts, and demonstrates durable activity over time.
  • The research provides new insights into the mechanisms of oxygen reduction on metal-nitrogen-carbon active sites, paving the way for designing efficient, low-cost, non-precious electrocatalysts for fuel cells and metal-air batteries.]
