Abstract

Two magnetic palladium catalysts i.e., Pd/Fe3O4/CB (carbon black) and Pd/Fe3O4/RGO (reduced graphene oxide), are prepared for Suzuki coupling reaction. The catalysts are characterized by FTIR, XRD and SEM. It shows that both Pd and Fe3O4 are well dispersed on the carbon black and reduced graphene oxide supports. The catalytic activity of Pd/Fe3O4/RGO catalyst is much higher than that of Pd/Fe3O4/CB catalyst for Suzuki coupling reaction of phenylboronic acid and bromobenzene, which indicates that the catalyst support reduced graphene oxide enhances the catalytic activity of Pd. Furthmore, the Pd/Fe3O4/RGO catalyst can be easily separated by an external magnet and reused for 8 times without obvious loss of its catalytic activity, which shows that the recyclability of the magnetic catalyst is good.
