Abstract: In this paper, graphene oxide-ferroferric oxide (GO-Fe₃O₄) composite was synthesized by a two-step process consisting of ion-exchange and coprecipitation and then it was deposited with palladium nanoparticles to obtain the lamellar catalyst Fe₃O₄-GO-Pd. The composition and structure were confirmed by XRD and SEM. The Heck reaction of bromobenzene and acrylic ester by the catalyst Fe₃O₄-GO-Pd were studied and the results showed that the yield can be 98.64% at 160℃ when performed with N,N-dimethylformamide (DMF) as solvent and it can still be 97.51% even after 4 recycling use.

Key words: graphene oxide; Fe₃O₄; palladium catalyst; Heck coulping reaction
