(a) Schematic test equipment of nitrate reduction reaction (NitRR) under a constant magnetic field. (b) The LSV curves of Ru NPs/N-C in the 0.1 M K2SO4 with 2.5 mM KNO3, Ru NPs/N-C in the 0.1 M K2SO4 with 2.5 mM KNO3 under magnetic field, Ru SAs/N-C in the 0.1 M K2SO4, Ru SAs/N-C in the 0.1 M K2SO4 under magnetic field and Ru SAs/N-C in the 0.1 M K2SO4 with 2.5 mM KNO3 under magnetic field. (c) NH3 yield rates and (d) FEs of Ru NPs/N-C, and Ru SAs/N-C at various applied potentials with or without magnetic field. (e) Comparison of the NH3 yield rates and FEs of Ru SAs/N-C under magnetic field with other reported electrocatalysts. (f) 1H NMR spectra of the electrolyte fed by K14NO3 and K15NO3 after NitRR. (g) Comparison of the amount of NH3 produced under four different conditions. (h) The long-term stability of Ru SAs/N-C with time-dependent current density curve and yield (inset) for the duration of 10 hours. (i) Cycling tests of Ru SAs/N-C at -0.6 V vs RHE.
