| Abstract: Using ammonium persulfate-initiated in-situ polymerization of pyrrole monomer to form a threedimensional porous aerogel as the carrier, and ferrocene as the metal precursor, a series of Fe/N/C catalysts with different iron loadings were prepared via high-temperature pyrolysis under argon atmosphere. The results demonstrated that the aerogel-supported catalysts exhibited excellent oxygen reduction reaction (ORR) activity and stability in acidic media. The optimal catalyst performance was achieved when the ferrocene loading was 12 mg, showing a half-wave potential of 0.691 V (vs RHE) and an average electron transfer number of 3.97, indicating a reaction pathway approaching the ideal four-electron process. Moreover, after 10 000 cycles of cyclic voltammetry testing, the half -wave potential of this catalyst only decayed by 11 mV, highlighting its superior electrochemical durability. |
