A new composite based on the incorporation of a metalloporphyrin within the UiO-66 metal-organic framework was synthesized using a one-pot method. The addition of Fe3O4 allowed for easy magnetic separation of the composite. The Fe3O4@CoTHPP@UiO-66 composite showed high efficiency in the oxidation of olefins and allylic alcohols.
One-pot facile synthesis of a new composite based on the incorporation of a metalloporphyrin within the UiO-66 metal-organic framework is reported. To enhance the catalytic activity of UiO-66, pore modification with (CoTHPP(OAC) = meso-tetrakis(4-hydroxyphenylporphyrinato) cobalt(ii)) was performed. For easy magnetic separation, Fe3O4 was introduced to the prepared composite. Characterization of the Fe3O4@CoTHPP@UiO-66 composite was performed by Fourier transform-infrared (FT-IR), ultraviolet-visible (UV-vis), atomic absorption spectroscopy (AAS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray (EDX) analysis, CHN elemental analysis, nitrogen adsorption-desorption isotherm (BET method), and X-ray diffraction (XRD) techniques. Oxidation of the olefins and allylic alcohols was done with tert-butyl hydroperoxide (TBHP) in acetonitrile with excellent efficiency (95% conversion) and 67% selectivity in the presence of Fe3O4@CoTHPP@UiO-66.
