摘要：

This study reports the fabrication and characterization of magnetically recyclable catalysts of Fe3O4-Pd nanocomposite as highly effective catalysts for reduction reactions in liquid phase. The characterization of Fe3O4-Pd MRCs were done by X-ray powder diffraction, A +/- nfrared spectroscopy, thermal analyzer, transmission electron spectroscopy, A +/- nductively coupled plasma, UV-Vis spectroscopy, vibrating sample magnetometer, respectively. The reduction of Pd2+ was accomplished with polyethylene glycol 400 (PEG-400) and Fe3O4 nanoparticles were prepared by co-precipitation of FeCI(3)a <...6H(2)O and FeCl(2)a <...4H(2)O. Thus formed Fe3O4-Pd MRCs showed a very high activity in reduction reactions of 4-nitro-aniline and 1,3-di-nitrobenzene in liquid phase. Magnetic character of this system allowed recovery and multiple use without significant loss of its catalytic activity.
