Manganese-based catalytic material on nickel foam substrate for electrochemical glycerol oxidation

Abstract

In this study, a manganese (Mn)-based electrode was synthesised on nickel foam via a hydrothermal method, and its electrocatalytic performance was evaluated for the glycerol oxidation reaction (GOR). The results revealed that Mn@NF exhibited excellent electrocatalytic performance toward GOR, requiring a potential of only 1.35 V vs. RHE to reach a current density of 10 mA.cm⁻² — substantially lower than that required for the oxygen evolution reaction. Furthermore, the catalyst achieved a hydrogen production rate of 0.625 mL.cm⁻².h⁻¹ at a potential of 1.42 V vs. RHE and maintained a stable current output over 10 hours of continuous operation. These findings demonstrate the promising potential of Mn@NF as an efficient electrocatalyst for GOR, offering a new pathway for energy-saving hydrogen production.
