Title
Recyclable polymer-stabilized nanocatalysts with enhanced accessibility for reactants
Abstract

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.
