英文摘要: Encapsulation of surfactant-free Pd nanoparticles (NPs) in the metal-organic framework material ZIF-8 hollow nanospheres was achieved. Pd@ZIF-8 hollow nanospheres showed excellent size-selective catalytic properties in the liquid-phase hydrogenation of olefins. As a result of the uniform pore size of the ZIF-8 shell (apertures of 3.4 angstrom), the catalyst showed high activity for the hydrogenation of 1-hexene (1.9x8.2 angstrom) but very low activity for larger molecules such as cis-cyclooctene (5.3x5.5 angstrom), trans-stilbene (4.2x11.3 angstrom), and triphenylethylene (9.1x9.2 angstrom). Other surfactant-free noble-metal nanoparticles could also be employed to produce NPs@MOFs for catalysis.
