Abstract

Nitrate electrocatalytic reduction to ammonia occurs with exceptional performance on ultrathin-sheet-assembled Fe80Ni20 nanoflowers, as described by Jason Lam et al. in their Research Article (e202500167). Mechanistic studies revealed that NO3<M-> preferentially adsorbs and is reduced to NO2<M-> on the Fe surface. Subsequently, NO2<M-> is efficiently hydrogenated to NH3 on the Ni surface. This in-tandem mechanism between Fe and Ni significantly enhances the electrocatalytic reduction of NO3<M-> to NH3.

外后盖:在超薄板组装的铁镍合金纳米花上,硝酸盐串联电化学还原为氨
正如Jason Lam等人在他们的研究文章(e202500167)中所描述的那样,在超薄薄片组装的Fe80Ni20纳米花上,硝酸盐电催化还原为氨具有优异的性能。机理研究表明NO3<;M->;优先吸附并还原为NO2<;M->;在铁表面。随后,NO2< M→在Ni表面有效地氢化成NH3。Fe和Ni之间的这种串联机制显著增强了NO3<;M->;氨。
