a LSV curves of FeSAC and PtNPs/FeSAC in Ar- and 1 vol% NO-saturated 0.5 M K2SO4 (pH =7.1, without iR-correction) at scan rate of 10 mV s−1. b NH3 yield and FE with 1 vol% NO over PtNPs/FeSAC at each given potential (without iR-correction). c The NH3 yield of PtNPs, NC, FeSAC and PtNPs/FeSAC. d NH3 yield of PtNPs/FeSAC under different conditions. e1H NMR spectra of the electrolyte fed by 15NO and 14NO for NORR over the PtNPs/FeSAC at −0.6 V (without iR-correction). f NORR cycling stability test over the PtNPs/FeSAC at −0.6 V (without iR-correction). g LSV curves of PtNPs/FeSAC test in MEA electrolyzer and H cell at scan rate of 10 mV s−1 (without iR-correction). h Corresponding NH3 yield and FE of PtNPs/FeSAC (without iR-correction). i Comparison of NORR performance with other electrocatalysts. Error bars indicate the relative standard deviations of the mean (n = 3). Source data are provided as a Source Data file.
