New and Recyclable Heterogeneous Ruthenium Magnetized Biochar Nanoparticlesas Catalyst for C-C Coupling Reactions

In this work Biochar nanoparticles were prepared from biomass pyrolysis. Then, it wasmagnetized and modified by ligand and rutenium to prepared catalyst (Ru-dithizone@biochar-Ni MNPs). Thisnanocatalyst has been characterized by variuse tequnics such as scanning electron microscopy (SEM),energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and vibrating sample magnetometer(VSM). Therefore, the catalytic activity of this catalyst was investigated as a practical, selective, and recyclablenanocatalyst in the Suzuki carbon-carbon coupling reaction in aqueous media. VSM curve of catalyst showedthat it could be easily recovered using an external magnet, and recycled for over and over times
