Catalytic oxidation of primary and secondary alcohols over a novel TCPP/Zn–Fe2O4@ZnO catalyst

Abstract

The catalytic activity of TCPP/Zn–Fe₂O₄@ZnO as a recyclable and high efficiency heterogeneous catalyst for oxidation of primary and secondary alcohols using aqueous hydrogen peroxide as a green oxidant under reflux conditions in CH₃CN was investigated. The catalyst could be magnetically recovered and reused for future runs without significant decrease in its activity and selectivity. The excellent selectivity (100%) was achieved under reaction conditions. Furthermore, X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), Fourier transform infrared (FT-IR), vibrating sample magnetometry (VSM), transition electron microscopy (TEM), scanning electron microscopy (SEM), X-ray fluorescence analysis (XRF) and energy dispersive X-ray analysis (EDX) were used for the catalyst characterization.
