palladium nanoparticles supported on uio-66: an efficient catalyst for suzuki coupling

nanoparticles of zirconium metal organic framework uio-66 (about 100 nm) have been used as proper supports for pd nanoparticles. highly dispersed pd nanoparticles (about 3–15 nm) were deposed on activated uio-66 metal organic framework using simple wet impregnation method at room temperature. uio-66 and the supported pd nanoparticles (pd/uio-66) were characterized by x-ray diffraction, n2 sorption, field emission scanning electron microscopy, transmission electron microscopy, energy dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy and inductively coupled plasma atomic emission spectroscopy. investigation of the catalytic performance of pd/uio-66 showed that the synthetic nanocomposites can effectively catalyze the suzuki–miyaura cross-coupling reaction of benzeneboronic acid with different aryl halides under mild reaction conditions using environmentally benign solvents.
