Pd and Au Immobilized On Amine-Functionalized Magnetite Nanoparticles: A Novel and Highly Active Bimetallic Catalyst for Hydrogenation
Avtar Changotra | Rajive Gupta | Satya Paul
Abstract: A novel heterogeneous Au-Pd bimetallic catalyst stabilized by amine-functionalized magnetite nanoparticles was synthesized by anchoring palladium and gold by a facile one-pot template-free method combined with a metal adsorptionreduction procedure. A highly efficient and recyclable heterogeneous bimetallic catalyst exhibits excellent catalytic activity for various aromatic nitro compounds and unsaturated compounds to their corresponding products under a H2 atmosphere at room temperature. The catalyst was found to be highly stable and passes hot filtration test successfully. The catalyst was characterized by FTIR; AAS; XRD; SEM and TEM. In addition; the catalyst can be easily separated and recovered with an external permanent magnet; and the reuse experiment shows that it can be used consecutively five times without significant loss in catalytic activity.
