摘要

This study investigates the dual functionality of titano-magnetite (Ti0.5Fe2.5O4) nanoparticles (NPs) synthesized via a green approach for both magnetic hyperthermia and energy storage applications. Spherical Ti0.5Fe2.5O4 NPs with an average crystallite size of 10–15 nm were successfully synthesized using pomegranate fruit shell extract as a natural reducing and capping agent. The synthesized NPs exhibited superparamagnetic behavior, with a saturation magnetization value of 32.2 emu/g at 300 K. When exposed to an alternating current (AC) magnetic field of 20–26.67  kA/m at 277 kHz, the NPs achieved a therapeutic temperature range of 38–39 °C. A specific loss power (SLP) of 27.90 W/g was recorded at a concentration of 1 mg/mL under an AC field strength of 26.67 kA/m. In addition to their hyperthermia potential, the NPs demonstrated promising electrochemical performance, with an energy density of 4.88  Wh/kg and a power density of 419 W/kg, confirming their applicability in supercapacitor devices. Cytocompatibility studies using NRK-52E cell lines at varying concentrations (10–50 mg/mL) confirmed the biocompatibility of the NPs. Overall, this work successfully demonstrates a green-synthesized nanomaterial with multifunctional potential for biomedical and energy-related applications.
