Outside Back Cover: In-tandem Electrochemical Reduction of Nitrate to Ammonia on Ultrathin-Sheet-Assembled Iron–Nickel Alloy Nanoflowers
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.
