Laser Vaporization And Controlled Condensation (Lvcc): Graphene Supported Pd/Fe3o4 Nanoparticles As An Efficient Magnetic Catalyst For Suzuki Cross – Coupling., Hany A. Elazab Dr
Chemical Engineering
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 …

Chemical and Biochemical Engineering Faculty Research & Creative Works
We report here a reliable green method for the synthesis of palladium nanoparticles supported on copper oxide as a highly active and efficient catalyst for Suzuki cross-coupling reaction. The experimental synthetic approach is based on microwave-assisted chemical reduction of an aqueous mixture of palladium and copper salt simultaneously using hydrazine hydrate as reducing agent. The catalyst was fully characterized using various techniques showing well-dispersed palladium nanoparticles. The catalytic activity and recyclability of the prepared catalyst were experimentally explored in the ligand-free Suzuki cross-coupling reaction with a diverse series of functionalized substrates. The synthesized Pd/CuO catalyst shows many advantages beside its …
