Magnetic core-shell-structured FeO@CeO as an efficient catalyst for catalytic wet peroxide oxidation of benzoic acid.

A magnetic core-shell-structured FeO@CeO catalyst was prepared by a simple solvothermal method and applied in the solid state for catalytic wet peroxide oxidation (CWPO) of benzoic acid. The obtained catalyst was characterized by N adsorption-desorption, X-ray diffraction (XRD), magnetic measurements, transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The experimental results showed that FeO@CeO possessed superior catalytic efficiency for CWPO of benzoic acid than that of FeO.
