This report contains the procedure implemented in the preparation of Fe3O4@SiO2/isoniazide/Pd as a novel magnetic nanocatalyst, in which isoniazide groups are utilized (as linkers) to secure palladium nanoparticles (Pd NPs) to the Fe3O4 exterior without agglomeration. The resultant catalyst was characterized through performing transmission electron microscopy (TEM), scanning electron microscopy (SEM), wavelength-dispersive X-ray spectroscopy (WDX), X-ray powder diffraction (XRD), Fourier transform infrared (FTIR), inductively coupled plasma (ICP), Energy-dispersive X-ray spectroscopy (EDS), vibrating sample magnetometer (VSM) and X-ray photoelectron spectroscopy (XPS). The catalytic behavior of Fe3O4@SiO2/isoniazide/Pd was investigated to synthesis of biaryl compounds by Suzuki coupling reactions. Interestingly, the novel catalyst was able to be recovered and recycled six times without any noticeable loss in activity.
