Abstract
Due to their special qualities, core-shell nanomaterials with two or more functionalities have drawn a lot of attention. Core-shell materials exhibit stronger combined electrical, optical, magnetic, and electronic characteristics than single-component nanomaterials thanks to the creation of the core-shell structure and the synergistic interaction between components. However, the formation of core-shell structures is often difficult due to the incompatibility between components, especially for lattice-mismatched core-shell structures. In this study, CoFe@CoFe2O4-N-C nanoparticles (∼150 nm) were successfully prepared via an ultrasonic atomization coupling pyrolysis process. This exhibits higher coercivity (108 Oe), saturation magnetization (52.3 emu/g) and Curie temperature (>400 K) than CoFe nanoparticles. At the same time, it exhibits high UV–Vis and infrared absorption characteristics and has good electronic properties as a direct band gap semiconductor material (bandgap of 2.87 eV). These characteristics suggest that CoFe@CoFe2O4-N-C NPs have a lot of potential in sectors like magneto-optics and absorbent materials.
