Abstract The integration of the hydrogen evolution reaction (HER) with glycerol oxidation (GOR) presents a promising strategy for production high‐value chemicals. Herein, strongly electronically coupled Co@V‐WO x material is presented an amorphous nanosheet morphology, synthesized via one‐step electrodeposition method. Experimental and theoretical investigations reveal that V doping induces robust electronic interactions between Co V‐WO host through formation Co─O─V/W interfacial bridge bonds, enhancing electron transfer capability superior activity. As result, catalyst achieves exceptionally low potential −102 mV 1.32 at 100 mA cm⁻ 2 , along remarkable Faradaic efficiency 95.4% formate 1.40 V. A two‐electrode electrolyzer based on demonstrates ≈100% evolution, exceeding 92.8% rate 59.4 mg h⁻¹ formate, as well outstanding stability over 300 h surpassing those previously reported Co‐based electrocatalysts. in situ spectroscopic analyses simulations further confirm facilitates kinetics by promoting active species key intermediates while lowering energy barriers electrolysis.
