Integrating glycerol oxidation with water electrolysis offers a sustainable route for hydrogen production while enabling 

concurrent generation of industrially relevant C1-C3 value-added materials. This system replaces kinetically sluggish

oxygen evolution reaction (OER) simultaneously delivering H2 at the cathode with high turnover frequency, thereby

lowering the overall cell voltage and enabling the valorization of glycerol, a major by-product of the biodiesel industry

. However, the development of an efficient bifunctional electrocatalysts capable of driving cathodic as well as anodic

half-cell reactions remains a key challenge. Herein, we present a cerium‑cobalt oxide composite modified with an 

amorphous carbon layer (Ce,Co-O/C) as an effective bifunctional catalyst for glycerol-assisted water electrolysis. 

The interfacial electron distribution across the Co Ce oxide heterojunction generated abundant redox-active sites and

accelerates reaction kinetics, while the conductive carbon layer facilitates rapid charge transfer and imparts improved 

stability. Consequently, the Ce, Co-O/C catalyst exhibited high formate selectivity at 1.4 V (vs RHE) at room temperature

and delivers a low cell voltage of 1.90 V at 100 mA cm2 in a symmetric Ce,Co-O/C || Ce,Co-O/C system, maintaining

operational stability over 100 h. This work provides a promising interface-engineering for designing self-supported 

bifunctional electrocatalysts toward integrated biomass assisted co-electrolysis systems.
