Abstract Electrocatalytic hydrogenation (ECH) of quinoline provides an eco‐friendly and prospective route to achieve the highly value‐added generation 1,2,3,4‐tetrahydroquinoline (THQ). Co element has been proven be efficient catalytic site for ECH quinoline, but rational regulation electronic structure active improve activity is still a challenge. Herein, hierarchical core–shell consisting NiCo‐MOF nanosheets encapsulated Cu(OH) 2 nanorods (Cu(OH) @CoNi‐MOF) constructed. The heterojunction promotes transfer interfacial charge optimizes site. introduction Ni significantly increases binding between Cu, preventing exfoliation sites from core, reducing reaction energy barrier rate‐determining step, thus resulting in superior reactivity durability. Besides, electrochemical reconstruction further modulates by forming multi‐metallic compound with low valence state (NiCoCu), achieving optimal performance conversion 99.5% THQ selectivity 100%. A flow‐cell system assembled, demonstrating prospect industrial application.

The synthesis of ammonia (NH3) through the electrocatalytic reduction nitrate (NO3–) represents a sustainable and environmentally friendly approach to production, with significant implications for agricultural chemical industries. Herein, we report fabrication cobalt–ruthenium nanoalloy embedded in an N-doped carbon matrix (CoRu/NC) NH3 synthesis. X-ray photoelectron spectroscopy (XPS) diffraction (XRD) results show strong electronic interaction between Co Ru, which is beneficial enhancing catalytic performance. Finally, it shows remarkable onset potential 0 V vs reversible hydrogen electrode (RHE) highest Faradaic efficiency 96% production at −0.2 RHE. high performance CoRu/NC attributed synergistic effect Ru nanoalloys encapsulated matrix. desirable component alloy could improve poor hydrogenation ability pure by providing atomic (H*), would facilitate intermediate nitrogen species during process. This work presents promising strategy efficient via reduction, offering insights into design advanced electrocatalysts energy environmental applications.
