Title
Biguanide/Pd(OAc)2 immobilized on magnetic nanoparticle as a recyclable catalyst for the heterogeneous Suzuki reaction in aqueous media
Abstract

Immobilization of Pd(II) ions on magnetite nanoparticle (MNP) has been simply achieved through a surface modification of Fe3O4 nanoparticle with a biguanide. This surface-modified nanoparticle was characterized by various techniques such as TEM, XRD, VSM, TGA, elemental analyzer, atomic absorption spectroscopy, N2 adsorption–desorption (BET and BJH), and FT-IR. This nanosolid exhibits excellent catalytic activity for heterogeneous Suzuki reaction in aqueous media, and could be easily separated by an external magnet and reused for several times. TEM study of the recovered catalyst showed the preservation of the support core–shell structure and the good dispersion of the produced palladium nanoparticles.
