Degradation of Methylene Blue by Ozone Oxidation Catalyzed by the Magnetic MnFeO@CoS Nanocomposite.

In this study, the MnFeO@CoS magnetic nanocomposite was prepared by a two-step hydrothermal method and used to catalyze the ozone oxidation degradation of methylene blue. It was characterized by XRD, EDS, SEM, FT-IR, and XPS. The results showed that the introduction of CoS made MnFeO grow uniformly on CoS nanosheets, which effectively prevented the agglomeration of MnFeO.
