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.
