Fig. 5 — a Linear scan voltammetry curves of L-Cu_xO-HC and glass carbon in 1 M KOH and 1 M KOH + 1 M KNO₃. b FE of NH₃ at different potentials. c NH₃ yield rate of L-Cu_xO-HC at different potentials. d NH₃ yield rate and current density of L-Cu_xO-HC in 1 M KOH + 1 M KNO₃ and 1 M KOH. e Partial NH₃ current densities of L-Cu_xO-HC in 1 M KOH + 0.1 M KNO₃, 1 M KOH + 0.5 M KNO₃ and 1 M KOH + 1 M KNO₃. f Stability test on L-Cu_xO-HC at −0.8 V vs. RHE for 10 cycles. g In situ ATR-FTIR measurement on L-Cu_xO-HC during NITRR and A_NO2-/A_NO2- + A_NH2OH. h Comparison of FE, product partial current density and yield with other reported catalysts (see the Supplementary Information for detailed references). Error bars represent the standard deviation of three independent measurements.
