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.

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.

“…1−8 The steady alterations inside the ferrites' chemical compositions could create apparent differences in the cation distributions. 6,9 The cation distribution depends on existing ions' atomic sizes, valences, and crystal fields. 6 Doping with divalent and trivalent cations inside the voids can significantly tune ferrites' structural, electrical, dielectric, and magnetic properties.…”

The exploration of aluminum (Al3+) ion substituted nickel–zinc–cobalt (Ni–Zn–Co) nanoferrites is still at the infancy stage, although the structural, electrical, and magnetic properties have been widely investigated. Single-phase cubic nanospinel ferrites of Ni0.4Zn0.35Co0.25Fe2–x Al x O4 (0 ≤ x ≤ 0.12) with space group Fd 3m were confirmed by the Rietveld refinement X-ray diffraction (XRD) data. Lattice constants displayed a declining trend with compositions x. The average particle size was found to range from 29 to 25 nm. Selected area electron diffraction (SAED) patterns were indexed according to space group Fd 3 m , indicating that nanoparticles are well crystallized. Samples’ modes of vibrations swung between redshift and blueshifts as detected in the Raman spectra. The saturation magnetizations (M s) were in the range of 59.85–86.39 emu/g. Frequency-dependent dielectric constants (ε′) and ac resistivity (ρ) measurement suggested that samples were highly resistive. These resistive nanoferrites with high saturation magnetizations may function effectively for multifaceted electronic devices.
