15N isotope labeling experiment and stability test. a 15N isotope labeling experiment. b Comparison of the Faradaic efficiency and ammonia yield rate using different feeding gases for the NRR at 0 V vs. reversible hydrogen electrode (RHE). The error bars correspond to the standard deviations of measurements over three separately prepared samples under the same conditions. c Faradaic efficiencies and NH3 yield rates of the single-atom dispersed Fe–N–C (FeSA–N–C) calculated after consecutive recycling electrolysis in N2-saturated 0.1 M KOH at 0 V vs. RHE for 1 h
