The global nitrogen cycle has been destroyed by the quickly growing anthropogenic emissions of nitrite-containing pollutants during past decades, which causes numerous unexpected environmental side effects and threatens human health. Compared with conventional nitrite removal methods featuring low efficiency, high cost, secondary pollution, electrocatalytic reduction reaction garnered significant attention offers an appealing solution for recovering balance. Moreover, it takes a step further to convert into recyclable nitrogen-containing fertilizer including ammonia urea. However, materials design mechanistic aspects such emerging complex reactions are yet be explored compared other well-studied primary as oxygen water splitting. To address this challenge, review provides comprehensive account sustainable electrosynthesis urea from ambient C–N coupling. two key reactions, namely production synthesis coreduction carbon dioxide, elaborated in detail, available catalysts focus discussion. current technical barriers potential research prospects domain, exploring excellent electrocatalysts activity selectivity, precisely controlling interfacial microenvironment, understanding in-depth mechanism, highlighted.

Abstract Sodium superoxide is considered the preferred discharge product for sodium‐air batteries (SABs) due to reversible electrochemistry of O 2 /O − redox pair and consequent low charge overpotential. However, air cathodes SABs based on mono‐metal systems have not yet achieved optimal adsorption products, leading suboptimal performance SABs. In this study, we present FeCo bimetallic alloy particles anchored carbon nanotubes (FeCo/C) as a demonstration bimetal‐based cathode Na‐air with FeCo/C can achieve overpotential gap 500 mV, high capacity 3392.20 mAh g −1 , excellent cyclic stability over 200 cycles (800 h). Ex‐situ spectroscopy confirms successful formation sodium main product, establishing clear correlation between composition verifying effectiveness cathode. Theoretical calculations further reveal that bimetallic‐based exhibits improved superoxide, significantly enhancing This work pioneers use bimetal strategies optimize products in SABs, paving way their practical application.
