Fig. 3

a LSV curves of Co/Co3O4 and Co/Co3O4/CoB with a scanning of 5 mV/s recorded in 0.1 M Ar-saturated and NO-saturated PBS (pH = 7.3 ± 0.1, with 90% iR-correction). b FENH3 and NH3 yield rate over Co/Co3O4/CoB at various cathodic potentials with a mass loading of 0.2 mg cm−2 at 25 °C. c Comparison of NORR performance between Co/Co3O4 and Co/Co3O4/CoB at -0.5 V vs. RHE. d NORR performance over Co/Co3O4/CoB and carbon paper (CP) under different conditions (O/C represents open circuit condition). The inset shows the 1H nuclear magnetic resonance spectra to quantify NH4+. e Stability test of Co/Co3O4/CoB at −0.5 V vs. RHE. f Comparison of electrocatalytic NORR performance of Co/Co3O4/CoB with other reported electrocatalysts in literature. The error bars denote the standard deviation derived from three independent measurements, with the central marker indicating the mean value.
