Electrochemical, Sensing and Environmental Assessments of CuFe2O4/ZnO Nanocomposites Synthesized via Azadirachta Indica Plant Extract

Abstract

<div>The CuFe2O4/ZnO nanocomposite (CZO NCs) has been successfully</div><div>synthesized by a facile one-pot green assisted approach using Azadirachtaindica</div><div>extract. These synthesized nanocomposites were characterized by different techniques;</div><div>Powder X-ray diffractometer (PXRD) confirms the formation of nanocrystalline</div><div>composite material with crystallite size in the range 15-30 nm. The surface morphology</div><div>of prepared nanocomposite materials was changed due to the plant extraction action as</div><div>reducing and capping agent studied by Scanning electron microscope (SEM), which</div><div>shows porous and spongy like structure. The photocatalytic performance of CZO NCs</div><div>was examined for their potential role in the photodegradation of Methylene Blue (MB)</div><div>dye under UV light. The result shows that the 1:2 molar CZO NCs is suitable for</div><div>excellent photocatalytic degradation performance of MB dye (98%). Electrochemical</div><div>analysis of prepared material was conducted with graphite electrode paste in 0.1 M KCl</div><div>electrolyte, which showed excellent performance in redox potential measured by Cyclic</div><div>Voltammetry and extended their sensor activities towards chemical and bio-chemicals</div><div>(Paracetamol and Glucose). These studies open a new platform to utilize a simple</div><div>approach for the preparation of multifunctional CZO NCs for their potential</div><div>applications in wastewater treatment and electrochemical studies.</div>
