A two-dimensional amide-linked covalent organic frameworks (2D-COFs) supported Pd catalysis system was synthesized. Fourier transformed Infrared (FTIR), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) are used to characterize the prepared catalyst. Electron microscopes (SEM and TEM) are employed to know the morphologies of the synthesized catalysts. The catalyst is an efficient heterogeneous catalyst for Suzuki-Miyaura coupling reaction, exhibits high catalytic activity for various aryl halides and aryl boronic acids in aqueous media at room temperature. More importantly, the catalyst with high stability could be easily recycled for at least nine runs without decrease of the catalytic activity.
