Electrochemical performance analysis of NiCuFe-LDHs nanosheets. a) LSV curves without (HER) and within (NitRR) 0.1 m KNO3 in 1.0 m KOH electrolyte. b) NitRR and HER overpotentials of NiCuFe-LDHs nanosheets at different current densities. The FE (c) and product yield (d) of CuFe-LDHs, NiFe-LDHs, and NiCuFe-LDHs nanosheets for NH3 synthesis in 1.0 m KOH with 0.1 m KNO3 electrolyte at different potentials. e) 1H NMR spectra using 15NO3− and 14NO3− electrolytes over NiCuFe-LDHs nanosheets. f) NH3 yield measured by NMR and UV-vis methods. g) The NH3 FE and NH3 yield in the durability test. h) The comparison of the NitRR performance of NiCuFe-LDHs nanosheets with previously reported advanced catalysts.
