Abstract Replacing the oxygen evolution reaction with alternative glycerol electro‐oxidation (GER) provides a promising strategy to enhance efficiency of hydrogen production via water electrolysis while co‐generating high‐value chemicals. However, obtaining low‐cost and efficient GER electrocatalysts remains big challenge. Herein, self‐supported N‐doped Co 2 NiO 4 nanoflakes (N‐Co NF) is proposed for electrocatalytic oxidation formate. The synergistic effect induced by interaction layered nanostructures on 3D‐printed Nickel‐Yttria‐stabilized zirconia (Ni‐YSZ) substrate amorphous nitrogen‐doping promotes anodic GER. N‐Co NF exhibits low potentials 1.07 1.18 V ( vs . RHE) drive 10 50 mA cm −2 , respectively. constituted two‐electrode electrolyzer NF//NiS‐Co‐NiP) displays excellent activity that only requires ultralow cell voltages 1.24 1.55 afford 200 respectively, high FE (97%) formate an durability (120 h). This study versatile approach manufacturing high‐performance Ni‐based electrocatalyst GER, paving way energy‐saving environmentally‐friendly co‐production value‐added chemicals hydrogen.
