CoFe₂O₄ magnetic nanoparticles: Synthesis by thermal decomposition of 8-hydroxyquinolinates, characterization, and application in catalysis

Cobalt ferrite magnetic nanoparticles are used as magnetic catalysts in several transformation. The magnetic nature of the NPs enables their easy recovery and reusability. In this study, a new, simple and effective route for the preparation of CoFe2O4 MNPs was presented. The method involved the thermal decomposition of Co and Fe precipitates synthesized simultaneously with 8-hydroxyquinoline. The material was characterized by several spectroscopic methods, such as XRD, Raman, Mossbauer and electron microscopy. Furthermore, the CoFe2O4 MNPs prepared was applicated as catalyst for the perimidine synthesis and recycled magnetically.
