• Here, we demonstrate that under ambient conditions, a nickel-iron layered double hydroxide nanosheet array can exhibit a promising NORR performance, delivering a maximal faradaic efficiency of 82% and a corresponding yield rate of 112 μmol h −1 cm −2 , along with high stability for over 30 h. This superior performance is further confirmed as a proof-of-concept for a Zn-NO battery, in which a peak power density of 1.8 mW cm −2 and a large NH 3 yield rate of 32 μmol h −1 cm −2 are observed. Theoretical analyses indicate that NiFe-LDH exhibits effective NO activation capacity and slow hydrogen evolution kinetics. A NiFe layered double hydroxide nanosheet array is designed as an efficient NORR catalyst for NH 3 electrosynthesis with a maximal FE of 82% and the highest yield rate of 1586.7 μg h −1 mg cat. −1 , exceeding most recently reported results.
