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

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