While the rare-earth nitride complexes enable highly efficient ammonia synthesis, they suffer from chemical sensitivity to air and moisture. Using Al-doped LaN as the model material, we show the impact of La−Al metallic bond formation on improving the catalysts’ durability under air and moisture without affecting original functionalities.

用于氨合成的化学耐久性镍和钴镧-氮化物基催化剂的方法

虽然稀土氮化物复合物能够实现高效的氨合成,但它们对空气和水分具有化学敏感性。我们使用掺杂铝的 LaN 作为模型材料,展示了形成 La-Al 金属键对提高催化剂在空气和湿气下的耐久性而不影响原有功能的影响。
