Electrochemical nitrogen reduction reaction (eNRR) offers a sustainable route for ammonia synthesis; however, current electrocatalysts are limited in achieving optimal performance within narrow potential windows. Herein, inspired by the heliotropism of sunflowers, we present biomimetic design Ru-VOH electrocatalyst, featuring dynamic Ru–O–V pyramid electron bridge eNRR wide range. In situ spectroscopy and theoretical investigations unravel fact that electrons donated from Ru to V at lower overpotentials retrieved higher overpotentials, maintaining delicate balance between N2 activation proton hydrogenation. Moreover, adsorption were found be enhanced moiety. The catalyst showcases an outstanding Faradaic efficiency 51.48% −0.2 (vs RHE) with NH3 yield rate exceeding 115 μg h–1 mg–1 across range −0.4 RHE), along impressive durability over 100 cycles. This M–O–V is also applicable other metals (M = Pt, Rh, Pd).
