A new magnetically recyclable catalyst, NiFe2O4–APTES–Pd(0) MRC, as highly effective catalysts for reduction reactions in liquid phase was fabricated and characterized. The chemical characterization of the product was done with X-ray powder diffractometer, Infrared spectroscopy, transmission electron microscopy, UV–Vis spectroscopy, thermal gravimeter and inductively coupled plasma. Magnetic character of the product was analyzed with vibrating sample magnetometer. The synthesized NiFe2O4–APTES–Pd(0) MRCs showed a very high activity in reduction reactions of 4-nitro aniline and 1,3-dinitrobenzene in liquid phase. NiFe2O4–APTES–Pd(0) MRC could be recovered by magnet and reused for ten runs for hydrogenetaion reaction of 4-nitro aniline and, 1,3-dinitrobenzene without significant degradation in the catalytic activity which shows the indicative of a potential applications of these catalyst in industry.
