Abstract Electrochemical nitrate reduction reaction (NO 3 − RR) provides a sustainable and efficient way to producing ammonia at ambient condition denitrifying wastewater. However, NO RR is still confronted with some barriers present, because of the sluggish kinetics competitive hydrogen evolution (HER). Particularly, it requires highly robust selective electrocatalysts, which steers complex multistep reactions toward process. Among various Co‐based electrocatalysts demonstrate rapid kinetics, steady catalytic performance, suppressive impact on HER for RR, attracting more attention. In this review, focused Cobalt‐based design corresponding strategies are summarized. detail, these can be concisely classified into five categories, including oxides hydroxides, alloys, metal, heteroatom‐doped materials, metal organic frameworks derivatives. Each category extensively discussed, its concepts ideas clearly conveyed through appropriate illustrations figures. Finally, scientific technological challenges as well promising constructing system in future discussed. It expected that review provide valuable insights guidance rational ultimately advancing their applications industrial scenario high current density, stability, energy efficiency.

Abstract The electrochemical CO 2 reduction reaction (CO RR) holds significant promise as a sustainable approach to address global energy challenges and reduce carbon emissions. However, achieving long‐term stability in terms of catalytic performance remains critical hurdle for large‐scale commercial deployment. This mini‐review provides comprehensive exploration the key factors influencing RR stability, encompassing catalyst design, electrode architecture, electrolyzer optimization, operational conditions. We examine how degradation occurs through mechanisms such valence changes, elemental dissolution, structural reconfiguration, active site poisoning propose targeted strategies improvement, including doping, alloying, substrate engineering. Additionally, advancements modifications membrane enhancements, are highlighted their role improving stability. Operational parameters temperature, pressure, electrolyte composition also play crucial roles extending lifespan reaction. By addressing these diverse factors, this review aims offer deeper understanding determinants RR, laying groundwork development robust, scalable technologies efficient dioxide conversion.

Abstract Electrocatalytic nitrate reduction (NO 3 RR) to ammonia (NH ) has great potential address the challenges caused by Habor‐Bosch process. However, sluggish kinetic, complex mechanisms and competitive reactions seriously reduce Faradaic efficiency (FE) yield of NH . Transition metal‐based compounds are promising catalysts for electrocatalytic NO RR, where anions can tune electronic structure metal cation sites. In this work, oxygen (O) phosphorus (P) introduced regulate nickel (Ni) reveal mechanism anion regulation in RR. The electrosynthesis performance is ranked as follows: Ni 2 P surpasses Ni, which turn outperforms NiO. Notably, nanosheets exhibit a maximum FE 97.4% 15.4 mg h − ¹ cm −2 Characterization theoretical calculation indicate that introduction moderately alters resulting reduced energy barriers rate‐limiting step RR improved H O decomposition generate active hydrogen, subsequently enhances production.
