Aqueous-phase oxidation of alcohols with green oxidants (Oxone and hydrogen peroxide) in the presence of MgFe2O4 magnetic nanoparticles as an efficient and reusable catalyst

Abstract

Nanomagnetic MgFe2O4 is an active, stable, and reusable catalyst for the oxidation of alcohols. The oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. The reactions were carried out in the presence of water as solvent and oxone (at room temperature) or H2O2 (at 60 ºC) as an oxidant. The catalyst was investigated by X-ray powder diffraction, scanning electron microscope, inductively coupled plasma and infrared techniques. Furthermore, the catalyst could be easily recovered and reused up to 7 runs without loss of activity.
