Electrocatalytic tandem nitrate reduction to ammonia (NO3 --to-NH3) offers a promising pathway for energy and environmental sustainability. Although considerable efforts have been presented modulate the reaction pathways enhanced NO3 --to-NH3 electrocatalysis, these advances often require relatively high overpotentials balance yield rate selectivity of NH3, resulting in remarkable inefficiency. Inspired by enzyme catalysis nature, herein enzyme-like electrocatalyst is designed consisting core Cu2O/Cu heterojunction surrounded mesoporous PdCu shell (Cu2O/Cu@mesoPdCu) that accelerated electrocatalysis positive potentials. Impressively, Cu2O/Cu@mesoPdCu nanozymes hold superior performance robust NH3 electrosynthesis fairly potential 0.10 V (versus reversible hydrogen electrode), having Faraday efficiency 96.2%, 13.3 mg h-1 mg-1, half-cell 46.0%. Kinetic studies, situ spectra density functional theory calculations revealed preferentially adsorbed - further reduced *NO2, while active radicals enriched on promoted multistep hydrodeoxygenation *NO2 within "semi-closed" microenvironment, both which synergistically enabled Moreover, this disclosed better more energy-efficient manner when coupling with thermodynamically favorable ethanol oxidation reaction.

Abstract Metal‐organic frameworks (MOFs) and their derivatives have shown broad application prospects in fields such as water electrolysis, electrochemical energy storage, sensing due to high specific surface area, tunable structures, abundant active sites. This article provides a comprehensive overview of our research group′s recent advancements developing MOF‐based electrocatalysts for Oxygen Evolution Reaction (OER) Urea Oxidation (UOR) at anodes, well Hydrogen (HER) cathodes during electrolysis. Furthermore, we integrated these catalysts into practical applications, including metal‐air batteries, lithium‐sulfur non‐enzymatic glucose sensors. To further demonstrate the innovative contributions work, systematically compare it with advanced work by other groups. Based on findings performance benchmarking analyses, identify critical challenges that must be addressed advance MOFs‐based toward next‐generation conversion sensing.
