a LSV curves of Fe-pdN-C(O), Fe-poN-C(O) and Fe-poN-C/Fe. b FECO and the corresponding j of Fe-poN-C/Fe at various potentials. (c) FECO and (d) CEE of Fe-poN-C/Fe compared with those of most state-of-the-art catalysts (see Table S4,5). e Stability tests of Fe-poN-C/Fe under an applied potential of −0.3 V. All measurements in flow cell are performed in 1 M KOH solution (pH 13.7, resistance is 1.68 Ω), and the catalyst mass loading is 1 mg·cm−2. Error bars in (b) represent the standard deviation of three independent measurements.
