Modulating the Active Hydrogen Adsorption on Fe─N Interface for Boosted Electrocatalytic Nitrate Reduction with Ultra‐Long Stability

Abstract The electrocatalytic reduction of nitrate (NO 3 − ) to nitrogen (N 2 ) is an environmentally friendly approach for efficient N‐cycle management (toward a nitrogen‐neutral cycle). However, poor catalyst durability and the competitive hydrogen evolution reaction significantly impede its practical application. Interface‐chemistry engineering, utilizing the close relationship between the catalyst surface/interface microenvironment and electron/proton transfer process, has facilitated the development of catalysts with high intrinsic activity and physicochemical durability. This study reports the synthesis of a nitrogen‐doped carbon‐coated rice‐like iron nitride (RL‐Fe 2 N@NC) electrocatalyst with excellent…
