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 cm, 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 and a large NH yield rate of 32 μmol h cm are observed. Theoretical analyses indicate that NiFe-LDH exhibits effective NO activation capacity and slow hydrogen evolution kinetics.
在此，我们证明在环境条件下，镍铁层状双氢氧化物纳米片阵列可展现出有前景的氮氧化物还原反应（NORR）性能，实现高达82%的最大法拉第效率以及112 μmol h cm的相应产率，同时具有超过30小时的高稳定性。这种优异性能进一步被证实为锌-一氧化氮电池概念验证，其中观察到峰值功率密度为1.8 mW cm以及32 μmol h cm的高氨气产率。理论分析表明，镍铁层状双氢氧化物展现出有效的一氧化氮活化能力以及缓慢的析氢动力学。
