This study investigates the electrocatalytic performance of Ni₃S₄ nanostructures for the oxygen evolution reaction (OER) in alkaline media. The Ni₃S₄ nanostructures were synthesized hydrothermally and analyzed with various characterization techniques. Electrochemical tests were used to assess OER activity, including linear sweep voltammetry (LSV), cyclic voltammetry (CV), electrochemical impedance spectroscopy, Tafel test, and chronoamperometry. Ni₃S₄ shows promising OER performance in alkaline media, with a low overpotential of 280 mV at 10 mA cm<SUP>-2</SUP>, high ECSA value of 375 cm², low R<SUB>ct</SUB> and R<SUB>s</SUB> values, and a small Tafel slope of 50 mV dec<SUP>-1</SUP>, indicating favorable kinetics. Notably, Ni₃S₄ maintained constant performance during 6 hours of continuous operation, demonstrating its potential as a robust and efficient electrocatalyst for OER applications in alkaline environments.
