Cobalt Nanoferrites: a Review on Synthesis, Characterization, and Applications

Cobalt nanoferrites are one of the most commonly used ferrites and have a wide range of applications. The present study involves several synthesis and characterization methods along with applications of cobalt ferrite nanoparticles. The selection of routes to prepare these nanoferrites was found to be dependent on the required properties of materials to be synthesized. All the available methods to synthesize the nanomaterials have their advantages and limitations that are discussed in detail. Numerous tools have been employed to analyze the properties of these nanomaterials. Among all these tools, XRD (X-ray diffraction) method and FT-IR spectroscopy are noticed as the most popular for precise structural analysis. The morphology has been determined using SEM (scanning electron microscopy) and TEM (transmission electron microscopy) in almost all studies. Owing to its exceptional characteristics, the cobalt nanoferrites have been found to be immensely utilized in multiple areas of applications such as microwave devices, MRI (magnetic resonance imaging), and hyperthermia.
