“…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.

Zinc ferrite (ZnFe2O4) nanoparticles were prepared by combustion method. The FT-IR, XRD and SEM with EDS were used to characterize the prepared sample. The characterization results confirm the successful synthesis of ZnFe2O4 nanoparticles with the particle size range of 24 – 30 nm. The temperature dependent DC conductivity of the sample has been studied in the temperature range 30-175 °C and AC conductivity was investigated between the frequencies of 10 Hz and 10 MHz. DC conductivity of the sample was increased while increasing temperature and AC conductivity was increased as the frequency increased.

A comparative study is made between the structure and electrochemical properties of Copper‐Zinc (Cu0.5Zn0.5Fe2O4) ferrite nanoparticles prepared by chemical co‐precipitation. The obtained ferrites are characterized by FT‐IR, XRD, BET, and SEM techniques. The single‐phase cubic formation of Cu0.5Zn0.5Fe2O4 nano ferrites without any impurity peaks is confirmed by XRD analysis. FT‐IR spectrum exposes the occurrence of vibrating modes analogous to the cubic‐spinel ferrite structure of Cu0.5Zn0.5Fe2O4 nano ferrites. The magnetic hysteresis curve displays the superparamagnetic nature of the Cu0.5Zn0.5Fe2O4 nano ferrites. The electrochemical properties of obtained ferrites are studied using cyclic voltammetry, charge‐discharge, and electrochemical impedance spectroscopy. The as‐synthesized Cu0.5Zn0.5Fe2O4 sample acts as an excellent electrode material in a supercapacitor with a high specific capacitance energy density and a power density.
