A new heterogeneous catalyst, magnetic amino-MIL-101(AI), was synthesized based on the reaction of NH2-MIL-101(Al) and silica coated magnetic nanoparticles, Fe3O4@SiO2. The prepared catalyst was characterized by UV-vis, Fr-IR, X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray (EDX) and inductively coupled plasma (ICP) methods. The catalytic activity of this new catalyst was investigated in the fixation of carbon dioxide with epoxides under atmospheric pressure at 100 degrees C. Excellent yields, short reaction times and reusability without significant decrease in its initial activity are the advantages of this noble catalyst. Moreover, magnetic property of the catalyst allows easy separation by using an external magnetic field.(C) 2017 Elsevier B.V. All rights reserved.
