Abstract

Electrochemical water splitting is a key method for clean, sustainable, and green hydrogen production, in which hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are the essential reactions underlying this phenomenon. These reactions are relatively sluggish in the perspective of reaction kinetics, which need to be catalyzed by electrocatalysts, like Pt/C, IrO₂, and RuO2. However, these are problematic electrocatalysts when large-scale applications are considered in terms of affordability and scarcity of the precious elements. In this study, we aim to develop more accessible and affordable electrocatalysts containing relatively abundant elements used in alkaline conditions. Accordingly, the electrocatalytic properties of the anti-perovskite structure Ni₃FeN compound were investigated. Single-phase stoichiometric Ni₃FeN powder was synthesized by hydrothermal precipitation of the mixed metal hydroxide and then by ammonolysis reaction. Phase purity and crystallinity were ensured by XRD and EDS. Additionally, particle size and morphology were examined with SEM. Finally, with LSV measurements for OER performance, overpotential at 10 mV/cm² and Tafel Slope were found to be 359 mV and 127.8 mV/dec, respectively. To determine ECSA and EDLC, CV was recorded in the non-faradaic region at various scan rates ranging from 5 to 800 mV/s. The results of EDLC and ECSA were 595 µF/cm² and 2.92 cm², respectively. HER performance was found not to be significant. All electrochemical tests in the study were carried out in an alkaline electrolyte. The outcome of this study suggests that the Nickel-Iron Nitride compound is a potential candidate as an electrocatalyst for OER under alkaline conditions.
