Nano-Fe3O4@SiO2 supported Pd(0) as a magnetically recoverable nanocatalyst for Suzuki coupling reaction in the presence of waste eggshell as low-cost natural base
In this study, a simple and efficient protocol was used for the synthesis of the nano-Fe3O4@SiO2 supported Pd(0) (Fe3O4@SiO2-Pd). SiO2 nanoparticles were prepared by the simple method from rice husk biomass as the source of biosilica. The Fe3O4@SiO2-Pd was characterized by a series of techniques such as SEM, EDS, XRD, TEM, ICP-AES, FT-IR and VSM. The Fe3O4@SiO2-Pd was used as a magnetically recoverable nanocatalyst for Suzuki coupling reaction in the presence of waste eggshell as low-cost solid base. The present method has significant advantages, such as use of natural and waste materials, use of an inexpensive catalyst, simple experimental procedure and low catalyst loading. In addition, the magnetically recoverable nanocatalyst can easily be recovered from the reaction system by using an external magnet and reused several times with insignificant loss of catalytic activity.
