In this research, a facile and reproducible approach was implemented for synthesis of palladium nano particles supported on Fe3O4 with remarkable activity as an ideal catalyst for Suzuki Cross – Coupling. Magnetite supported Pd nano particles reveals a high activity towards Suzuki coupling reactions as it could be recycled up to seven times with the same high catalytic activity. This adopted method of catalyst synthesis has so many advantages as reproduciblity, and reliability of the adopted synthetic method. The produced catalyst has unique magnetic properties to facilitate the catalyst recovery from the reaction mixture through using a strong magnet as an external magnetic field.
The synthetic approach adopted in this research is based on the Microwave-assisted irradiation (MWI). The distinctive advantage of adopting this approach rather than the conventional heating is the simplicity of reaction addition at mild reaction conditions.
Moreover, this method offers high rate of recyclability as the catalyst has a high recyclability rate up to seven times under mild reaction conditions, and also reproducibility. The magnetic properties of the prepared catalyst increase the ability of the products separation and purification from catalyst and other side products leading to an increase in the economic value of the catalyst. The prepared catalyst was characterized by various spectroscopic techniques including; X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Vibrating Sample Magnetometer (VSM) and transmission electron microscopy (TEM).
