Abstract

Although Urea oxidation reaction (UOR) with favorable thermodynamic potential has been well-acknowledged as a feasible alternative to slow oxygen evolution reaction for hydrogen production through water splitting, but the shortage of low-cost and high efficiency electrocatalysts restricts its practical development. In this research, a free-standing nickel–iron-phosphide (NiFeP) nanosheets electrocatalysts on nickel foam is synthesized by electrodeposition method. The presence of phosphide (P) causes nickel–iron (NiFe) to evolve from crystalline to amorphous structures. The NiFeP electrocatalysts with nanosheets structure exhibit reliable electrocatalytic activities toward UOR with small potential of 1.397 V at 10 mA cm−2, low Tafel slope of 60.1 mV dec−1 and outstanding catalytic stability in 1.0 M KOH with 0.33 M urea solution. More impressively, the electrochemical activation energy (Ea) of UOR for the NiFeP electrocatalyst (35.6 kJ mol−1) is much lower than that of NiFe electrocatalyst (52.1 kJ mol−1). The phosphorus doping triggers the electronic structure of Ni and Fe site reconstruction, which is conducive to accelerating charge and mass transport, and then contributes to the enhanced electrocatalytic performance. Furthermore, the formation of amorphous structure and nanosheets structure by the incorporation of phosphorus contributes to the improved intrinsic activity of NiFeP for UOR.
