Dr. Yanfei Wang, Dr. Ankush V. Biradar and Prof. Tewodros Asefa Assembling Nanostructures for Effective Catalysis: Supported Palladium Nanoparticle Multicores Coated by a Hollow and Nanoporous Zirconia Shell ChemSusChem 5
Coating glassy caves: A highly efficient and recyclable nanocatalyst, consisting of SiO2 nanosphere-supported Pd nanoparticle multicores, coated with a hollow and nanoporous ZrO2 shell, is synthesized. The catalyst shows excellent catalytic activity in the hydrogenation of olefins and nitro groups, even at room temperature and moderate hydrogen pressure, owing to the small and stable Pd nanoparticles and their bare surface. The nanocatalyst also proves to be stable and can be recycled several times.
