    for Selective Hydrogenation
  title_type: original
  lang: en

## Description

- description: Developing efficient catalysts for selective hydrogenation of molecules
    bearing multiple reducible functional groups remains a major challenge. Palladium
    (Pd) nanoclusters are promising candidates owing to their strong H2 activation
    ability, broad substrate compatibility, and unique surface properties. However,
    the controlled synthesis of small Pd nanoclusters with accessible, coordinatively
    unsaturated active sites remains difficult as they are prone to aggregation. In
    this study, we present a strategy to fabricate surface-exposed Pd nanoclusters
    confined within a ring-shaped polyoxometalate (POM) via a mild solid-state reduction
    process (1 atm H2, ~25 °C). The resulting Pd nanocluster exhibits exceptional
    chemoselectivity in the hydrogenation of multifunctional substrates by preferentially
    adsorbing C=C and C≡C bonds on its discrete, exposed Pd surface with a well-defined
    coordination environment. Importantly, the rigid POM framework considerably stabilizes
    Pd nanocluster, enabling excellent reusability over multiple catalytic cycles.
    This study demonstrates a molecular templating approach for constructing robust
    and chemoselective metal nanocluster catalysts, offering new opportunities in
    the design of hydrogenation systems.
