Sm Doped Cu–Ni Spinel Ferrite Nanoparticles for Hyperthermia and Photocatalytic Applications

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(7), P. 7028 - 7042

Published: March 15, 2024

This work explored the versatility of nanocrystalline Sm-doped Cu–Ni spinel ferrites in different applications, with a special emphasis on hyperthermia and photocatalytic activities. By incorporating Sm dopants at varied percentages nanosized ferrites, magnetic, electrical, structural properties host were tailored to make them versatile materials applications various technological fields. Careful examination powder X-ray diffractograms (XRDs) ensured presence pure cubic crystal structure for all synthesized ferrite samples. Obtained high-resolution transmission electron microscopy images also validated XRD results along mean size, morphology, regularity both shape size examined thoroughly. With increasing percentage, average nanoparticles reduced, which is verified by gradual increase bandgap as obtained from Tauc plots. Additionally, it found that hopping electrons under an applied alternating electric field was main process charge conduction samples, effects grain boundaries dominated over grains determining dielectric responses. The incorporation Sm3+ ions owning less magnetic moment compared Fe3+ reduced coercive saturation magnetization gradually noticed M(H) loops. aroused superparamagnetic phenomenon room temperature due doping favored controlled through induction heating. Bare doped samples showed excellent heating, obeying clinical safety limits. In addition, photon-mediated degradation ciprofloxacin (CIP) antibiotic conducted using as-prepared 15% sample sufficient remove 95.8% CIP solution 60 min. Moreover, displayed antioxidant antidiabetic properties. Hence, nanoferrites are especially photocatalysis.
