Abstract

An efficient magnetic carbon nanocomposite supported Pd nanoparticle catalyst has been prepared by a three-step process in this report. The morphology, inner structure, and magnetic properties of all products were studied with transmission electron microscopy, X-ray powder diffraction, Fourier translation infrared spectroscopy, X-ray photoelectron spectroscopy, and vibrating sample magnetometer. The Suzuki and Heck coupling reactions were used to demonstrate the catalytic efficiency of the as-prepared Pd/Fe3O4@C (Pd/MFC) nanocomposite catalyst. The results showed that the catalyst is completely recoverable with the simple application of an external magnetic field and the catalytic efficiency shows no obvious loss for Suzuki and Heck coupling reactions even after five repeated cycles.
