Bifunctional Cr-MOF catalysts containing palladium nanoparticles (NPs) have been prepared. Combining the high activity of Pd NPs and base sites in MIL-101-NH2, the catalysts (Pd@MIL-101-NH2) exhibited distinct catalytic activity in a one-pot Suzuki-Knoevenagel reaction. Pd@MIL-101-NH2 has been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and fourier transform infrared spectroscopy (FT-IR). Various substituted phenylboronic acids were used to research the one-pot reaction. The results were highly satisfactory, not only got high yield, but reduced reaction time. Leakage experiments further demonstrated that there is no leaching of active palladium nanoparticles during the reactions. Catalysts could be reused for at least five cycles and activity is not significantly decreased.
