A reproducible, reliable, and highly efficient synthetic approach was implemented for synthesis of palladium nanoparticles supported on a binary composite of Fe3O4 and graphene (Pd-Fe3O4/G). This unique catalyst was tested for being used as a highly efficient active catalyst for being used in Suzuki cross – coupling reactions. It was found that this graphene supported Pd/Fe3O4 nanoparticles (Pd-Fe3O4/G) has a remarkable catalytic activity towards Suzuki coupling reactions. This catalyst could be recycled for up to three times with high catalytic activity. The catalyst was prepared using LVCC synthetic approach; the prepared catalyst was found to be highly magnetic which enabled the separation process of the catalyst via applying an external magnetic field using a strong magnet. This adopted synthetic approach has many advantages including recyclability, mild reaction conditions, and reproducibility. The high catalytic performance is due to the catalyst-support strong interaction. Moreover, the defect sites found on reduced GO nanosheets act as nucleation centers providing a platform to anchor Pd and Fe3O4 nanoparticles and hence avoid the potential agglomeration and subsequently the anticipated decrease in the catalyst catalytic
