NiFe Oxide-Based Electrodes Loaded on Indium Tin Oxide as EffectiveElectrocatalysts for Oxygen-Evolution Reaction

The oxygen-evolution reaction (OER) is a vital process in energy storage applications such asmetal-air batteries and water splitting [۱,۲]. NiFe oxide-based electrodes have gained significantattention for OER due to their promising features [۳]. In this study, we investigated theeffectiveness of NiFe oxide loaded on indium tin oxide as an electrocatalyst for OER in thepresence of NaHCO۳. The electrocatalyst was characterized using various techniques, includingRaman spectroscopy, diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), scanningelectron microscopy (SEM), and energy-dispersive X-ray spectrometry (EDX). Our findingsrevealed that NiFe oxide loaded on indium tin oxide serves as an effective and durableelectrocatalyst for OER in the presence of NaHCO۳. Furthermore, our results suggest that theelectrolysis of NaHCO۳ solution offers a highly promising alternative for producing oxygen andhydrogen compared to corrosive acidic or alkaline solutions. These findings demonstrate thepotential of NiFe oxide-based electrodes for OER and offer insights into developing sustainableand efficient energy storage systems
