In this study, a controlled synthesis of hyper-crosslinked monodisperse microsphere with homogeneous mesoporous aperture about 6 nm is presented. After supported with palladium, the catalyst was performed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and nitrogen adsorption and desorption surface area analyses. The results showed that HCP-(PS-DVB)-Pd(0) possessed high catalytic activity for Suzuki-Miyaura cross-coupling reaction at room temperature, and the catalyst also show excellent reusability. After recycled for 10 times, the yield can maintain above 95% and the surface areas can still reach 480.5 m2·g-1. These results suggest that the HCP-(PS-DVB)-Pd(0) catalyst has potential applications in synthetic and industrial chemistry.

Key words: hyper-crosslinked PS-DVB, monodisperse microsphere, Pd nanoparticles catalyst, Suzuki cross-coupling reaction
