This study investigates the effect of size variation in CeO2/MgFe2O4 nanocomposites on their electrochemical performance and cytotoxicity. The nanocomposites were synthesized using a combustion process and different calcined temperatures to adjust the particle size. The results show that the nanocomposites exhibit good biocompatibility and favorable electrochemical performance, suggesting their potential for biological applications.
In this study, we investigated the effect of size variation in CeO2/MgFe2O4 nanocomposites (NCs) on their electrochemical (EC) performance and cytotoxicity. To adjust particle size, the NCs were synthesized using an auto-combustion process and subsequently at various (500, 600, 700, and 800 degrees C) calcined temperatures (CTs). The crystallite size was determined using X-ray diffraction (XRD), and the NCs spherical shape was validated using field emission-scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). The chemical components on the surface of the NCs were discovered using an X-ray photoelectron spectroscopy (XPS). The different size distributions of CeO2/MgFe2O4 NCs as electroactive materials in supercapacitors and measured their EC performance in 1 M KOH using cyclic voltammetry (CV), galvanostatic charge/discharge (GCD) and electrochemical impedance spectroscopy (EIS). The CeO2/MgFe2O4 NCs revealed a good cell survival rate in cytotoxicity studies, showing their biocompatibility. The NCs were found to be harmless to HDF and MDAMB-231 cancer cell lines, highlighting their potential for biological applications in the future.
