Enhanced Electrochemical Performance of MnCo_1.5Fe_0.5O₄Spinel for Oxygen Evolution Reaction through Heat Treatment.

ABSTRACT: MnCo_1.5Fe_0.5O₄ spinel oxide was synthesized using the sol-gel technique, followed by heat treatment at various temperatures (400, 600, 800, and 1000 °C). The prepared materials were examined as anode electrocatalysts for water-splitting systems in alkaline environments. Solid-state characterization methods, such as powder X-ray diffraction and X-ray absorption spectroscopy (XAS), were used to analyze the materials' crystallographic structure and surface characteristics. The intrinsic activity of the MnCo_1.5Fe_0.5O₄ was fine-tuned by altering the electronic structure by controlling the calcination temperature, and the highest activity was observed for the sample treated at 800 °C.
