A Review on Developments in Spinel Ferrite Nanomaterials: Synthesis, Characterization, and Diverse Applications

This paper explores a review on the synthesis, characterization, and wide range of uses of doped spinel ferrite nanoparticles, highlighting their important role in biosensors, industrial electronics, water treatment, transducers, transformers, cancer treatment, and magnetic resonance imaging. Substitution in the lattice sites of spinel ferrites with metals improves their electrical and magnetic characteristics, which makes them useful for a variety of applications, including microwave absorbers, magnetic fields, and biomedical devices. Spinel ferrites' physical characteristics can be altered to produce better performance by substitution of metallic atoms. Oxygen vacancies, crystal defects, and unsaturated metal cations exist on the surface of spinel ferrite magnetic nanomaterials. For this reason, hydroelectric cells that dissociate water molecules at room temperature have been fabricated using these materials. The dissociation of water molecules generates electricity in hydroelectric cells, which is revolutionary research of 21st century. The objective of this review is to assist researchers in maximizing the effectiveness of these adaptive materials by offering information on the selection of suitable magnetic ferrites according to anticipated applications.
