This study includes the procedure performed for the Pd@PS-Met preparation as a novel polymeric nanocatalyst, in which to entrapped palladium nanoparticles (Pd NPs) without agglomeration, metformine groups are applied (as linkers). The obtained catalyst could be evaluated using transmission electron microscopy (TEM), wavelength-dispersive X-ray spectroscopy (WDX), scanning electron microscopy (SEM), X-ray powder diffraction (XRD), inductively coupled plasma (ICP), fourier transform infrared (FTIR), and Energy-dispersive X-ray spectroscopy (EDS). For Suzuki cross-coupling reaction, the catalyst showed an excellent catalytic stability and activity in water under ambient condition. Additionally, this novel entrapped palladium catalyst was recovered by an easy filtration and reapplied several times without considerable activity loss.
