Pd on Amine-Terminated Ferrite Nanoparticles:  A Complete Magnetically Recoverable Facile Catalyst for Hydrogenation Reactions^†

The present communication reports a facile route for Pd(0) immobilization on the surface of amine-terminated Fe₃O₄ and NiFe₂O₄ nanoparticles for a series of hydrogenation reactions. The catalysts are completely recoverable with the simple application of an external magnetic field, and the efficiency of the catalyst remains unaltered even after 10 repeated cycles for each of the reactions.
