New Palladium - ZrO Nano-Architectures from Thermal Transformation of UiO-66-NH for Carbonylative Suzuki and Hydrogenation Reactions.

The new nanocomposites, Pd/C/ZrO , PdO/ZrO and Pd/PdO/ZrO , were prepared by thermal conversion of Pd@UiO-66-Zr-NH (MOF) in nitrogen or air atmosphere. The presence of Pd nanoparticles, uniformly distributed on the ZrO or C/ZrO matrix, was evidenced by transmission electron microscopy, scanning electron microscopy (SEM), Raman and X-ray Photoelectron Spectroscopy (XPS) methods. All pyrolysed composites retained the shape of the MOF template.
