a Linear scan voltammetry curves of L-CuxO-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-CuxO-HC at different potentials. d NH3 yield rate and current density of L-CuxO-HC in 1 M KOH + 1 M KNO3 and 1 M KOH. e Partial NH3 current densities of L-CuxO-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-CuxO-HC at −0.8 V vs. RHE for 10 cycles. g In situ ATR-FTIR measurement on L-CuxO-HC during NITRR and ANO2-/ANO2- + ANH2OH. 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.
