Résumé

Palladium nanoparticles stabilized by choline-based ionic liquids in glycerol were prepared from Pd(II) precursors by simply heating at 80 °C under argon; in this process, the water present in the ionic liquid was found to be the responsible for the reduction of Pd(II) into zero-valent palladium species. Palladium nanoparticles were fully characterized in both liquid phase and solid state. The as-prepared metal nanoparticles exhibited remarkable catalytic activity in hydrogenation processes for a significant variety of functional groups (alkenes, alkynes, nitro derivatives, benzaldehydes, aromatic ketones). Highlights  Palladium nanoparticles in glycerol stabilized by novel choline-based ionic liquids.  Characterization of palladium nanoparticles both in solid and liquid phase.  Palladium nanoparticles showing high catalytic activity in hydrogenation reactions.  Selective hydrogenations for non-conjugated alkynes.  Efficient reduction of carbonyl derivatives.
