Abstract Lithium‐sulfur (Li‐S) batteries are recognized as a most promising energy storage technology for their high theoretical density, abundant sulfur resources, and environmental friendliness. Nonetheless, practical applications of Li‐S currently hindered by obstacles such the shuttle effect lithium polysulfides (LiPSs), sluggish reaction kinetics, formation Li dendrites. Heterostructured electrocatalysts can achieve synergistic adsorption‐catalysis LiPSs regulating component composition to accelerate electrochemical guide uniform deposition Li. Electrospinning has emerged versatile approach precise fabrication heterostructured nanomaterials, advantages including tunable composition, controlled fiber diameter, diverse pore structures, flexible morphological heterogeneous interfacial design. In this contribution, latest research progress on heterostructures constructed electrospinning is reviewed. Initially, definition outlined mechanisms promote kinetics in analyzed. Subsequently, principles influencing factors constructing based discussed. The application cathodes, separators, anodes further comprehensively Finally, issues identified, corresponding effective solutions provided. This review intended inspire design construction efficient batteries.

Relay catalysis represents significant efficacy in alleviating competition among different reactants during coupling reactions. However, a comprehensive understanding of the reaction mechanism underlying relay for urea electrosynthesis remains challenging. Herein, we have developed catalyst (CuAC-CuSA@NC) comprising Cu atomic clusters (CuAC) with satellite Cu─N4 single atoms (CuSA) sites on nitrogen-doped porous interconnected carbon skeleton (NC), enabling elucidation process co-reduction CO2 and NO3 -. The designed CuAC-CuSA@NC exhibits an approximately threefold higher yield rate compared to that CuSA@NC at -1.3 V versus RHE. Ex-situ experimental results in-situ attenuated total reflection surface-enhanced infrared absorption spectroscopy analysis reveal formation sequence between *NH2 *NH2CO species increasing reduction potential. combination theoretical calculations further elucidates pathway involves "CuAC" facilitating conversion *NO3 *NOx, followed by hydrogenation form *H from water dissociation promoted "CuSA" sites, which subsequently couples *CO2 produce urea. This work provides novel insights into investigation reactions, but not limit to, synthesis.

Abstract Ammonia is a widely produced chemical globally, primarily used in fertilizers and products. Recently, it has gained attention as green hydrogen carrier due to its high content energy density. However, the conventional Haber‐Bosch process for ammonia synthesis energy‐intensive, requiring temperatures pressures. Also, significant source of CO 2 emissions. To address these environmental concerns, electrochemical nitrate reduction reaction (NO 3 RR) emerged promising approach production, utilizing from wastewater renewable sources. While most previous research focuses on cathodic needs emphasize importance optimizing anodic reactions NO RR systems reduce consumption improve efficiency. The oxygen evolution (OER), typically coupled with RR, kinetically slow requires standard potential. Therefore, alternative lower potentials not only save but also yield valuable byproducts. Furthermore, coupling like zinc oxidation allows power generation, where positive cell potential indicates spontaneous reactions. This dual approach, saving opens new pathways sustainable reducing overall demands while supporting shift toward systems.
