“…Magnetic nanoparticles have increased significant enthusiasm for different areas, for example, ferrofluids, magnetic drug transportation, magnetic separations, magnetic data storage devices, magnetic resonance imaging (MRI), and magnetic fluid hyperthermia treatment for malignant growth [1][2][3][4][5][6][7][8]. Magnetic nanoparticles are alluring catalyst since they can be isolated from the response medium by applying an outside magnetic attractive field.…”

A profoundly effective magnetically recoverable nano zinc ferrite nanocatalyst was fabricated by means of sol-gel auto ignition strategy. The synthesized nanocatalyst has been completely portrayed by standard techniques for structural, morphological, compositional, surface, magnetic, dielectric, optical and photoluminescence properties individually. The x-ray diffraction pattern affirmed the arrangement of cubic spinel structure with an average crystallite size of 21 nm. FE-SEM images uncovered the circular morphology with nanometric average grain measure (37 nm). The surface area, pore volume and pore radius was observed to be 39.812 m 2 g −1 , 3.41 cc g −1 and 1.34 nm individually from BET analysis. VSM investigation demonstrated the superparamgnetic nature of the prepared sample with moderate magnetization value and negligible coercivity. The optical band gap deduced from UV-vis spectra was observed to be 2.098 eV. Every one of these properties of zinc nanoferrite makes them brilliant contender for microwave radiation absorption. Further, a proficient and versatile microwave irradiated solvent free synthesis of chalcone derivatives has been developed using prepared zinc nanoferrite catalyst. The remarkable highlights of this new protocol are solvent free reaction, economical cheapness, eco-friendliness, high yields, reduced reaction times and easy recovery and reuse of zinc ferrite nanocatalyst.

“…In the field of nanomagnetism, the spinel ferrites are important materials because they exhibit unusual magnetic and electrical properties in comparison with their bulk counterpart [ 4 , [10] , [11] , [12] ]. Nanocrystalline spinel ferrites have been demonstrated as useful material for hyperthermia [ 13 , 14 ], detection of COVID-19 [ 15 ], visible light-enabled photodegradation [ 16 ] and, the catalyst for the synthesis of chalcones [ 17 ]. The molecular formula of spinel-type ferrite is MFe 2 O 4 (M = Co, Ni, Mn, Mg, or other divalent cations) [ 18 ].…”

This paper reports the structural, morphological, spectroscopic, dielectric, ac conductivity, and impedance properties of nanocrystalline Mn 1-x Zn x Fe 2 O 4 . The nanocrystalline Mn–Zn ferrites were synthesized using a solvent-free combustion reaction method. The structural analysis using X-ray diffraction (XRD) pattern reveals the single-phase of all the samples and the Rietveld refined XRD patterns confirmed the cubic-spinel structure. The calculated crystallite size values increase from 8.5 nm to 19.6 nm with the Zn concentration. The surface morphological analysis using field emission scanning electron microscopy and the transmission electron microscopy confirms the nano size of the prepared ferrites. X-ray photoelectron spectroscopy was used to study the ionic state of the atoms present in the samples. Further, the high-resolution Mn 2p, Zn 2p, Fe 2p, and O 1s spectra of Mn 1-x Zn x Fe 2 O 4 does not result in the appearance of new peaks with Zn content, indicating that the Zn substitution does not change the ionic state of Mn, Zn, Fe, and O present in nanocrystalline Mn 1-x Zn x Fe 2 O 4 . The investigated electrical properties show that the dielectric constant, tan δ and ac conductivity gradually decrease with increasing Zn substitution and the sample Mn 0 · 2 Zn 0 · 8 Fe 2 O 4 has the lowest value of conductivity at 303 K. The ac conductivity measured at different temperatures shows the semiconducting nature of the ferrites. The impedance spectra analysis shows that the contribution of grain boundary is higher compared with the grain to the resistance. The obtained results suggest that the Zn substituted manganese ferrite nanoparticles can act as a promising candidate for high-frequency electronic devices applications.

Highlights Crystallites sizes of nanoparticles synthesized via ultrasound irradiation were less than 40nm. Ms and Hc of nanoparticles obtained at 25℃ were higher than at 50℃ under the same power. The samples exhibited the highest Ms at 25℃ and the lowest Hc at 50℃ both for 60W. The ultrasonic irradiation had a positive effect on improving the ferrite magnetic properties.
