Abstract 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 Å), the catalyst showed high activity for the hydrogenation of 1‐hexene (1.9×8.2 Å) but very low activity for larger molecules such as cis ‐cyclooctene (5.3×5.5 Å), trans ‐stilbene (4.2×11.3 Å), and triphenylethylene (9.1×9.2 Å). Other surfactant‐free noble‐metal nanoparticles could also be employed to produce NPs@MOFs for catalysis.
