Recyclable polymer-stabilized nanocatalysts with enhanced accessibility for reactants

Immobilization of nanocatalysts in polymers and the use of such polymer-metal nanocomposites in catalytic reactions is interesting due to their high activity and recyclability. A nanocomposite material containing Pd-NPs has been prepared by Intermatrix Synthesis (IMS) technique by using a functional polymer (granulated ion exchange resin). The resulting nanocomposite material contains immobilized core–shell Pd@Co-NPs distributed mainly by the surface of the polymer. Such arrangement enhances the accessibility of the nanocatalysts for reagents in catalytic applications. It has been shown that the Suzuki-Miyaura coupling reaction proceeds under mild reaction conditions when using the new NC material.

► In this study we synthetized both monometallic (Co) and bimetallic (Pd@Co) metal nanoparticles inside various functional polymers.
► The synthesis was made by using a simple and efficient Intermatrix Synthesis technique coupled with the Donnan exclusion effect.
► We examined the location of metal nanoparticles which is near the surface of nanocomposite, confirmed by SEM and TEM analysis.
► Core shell Pd@Co nanoparticles synthesis results in the formation of the easily recoverable and recyclable catalysts.
► Pd@Co nanocomposites were catalytically tested by Suzuki Cross-Coupling reaction.
