One of the most effective electrocatalysts for electrochemical oxidation reactions is NiMn<sub>2</sub>O<sub>4</sub> spinel oxide. Here, a 3-D porous substrate with good conductivity called carbon felt (CF) is utilized. The composite of NiMn<sub>2</sub>O<sub>4</sub>-supported carbon felt was prepared using the facile hydrothermal method. The prepared electrode was characterized by various surface and bulk analyses like powder X-ray diffraction, X-ray photon spectroscopy (XPS), Scanning and transmitted electron microscopy, thermal analysis (DTA), energy dispersive X-ray (EDX), and Brunauer-Emmett-Teller (BET). The activity of NiMn<sub>2</sub>O<sub>4</sub> toward the electrochemical conversion of ethylene glycol at a wide range of concentrations was investigated. The electrode showed a current density of 24 mA cm<sup>-2</sup> at a potential of 0.5 V (vs. Ag/AgCl). Furthermore, the ability of the electrode toward hydrogen evaluation in an alkaline medium was performed. Thus, the electrode achieved a current density equal 10 mA cm<sup>-2</sup> at an overpotential of 210 mV (vs. RHE), and the provided Tafel slope was 98 mV dec<sup>-1</sup>.
