Magnetically Separable and Recyclable Fe(3)O(4)-Supported Ag Nanocatalysts for Reduction of Nitro Compounds and Selective Hydration of Nitriles to Amides in Water

As hybrid nanostructures have become more important in many fields of chemistry, Ag nanoparticles (NPs) are being increasingly immobilized onto Fe(3)O(4) microspheres in situ. Structural characterization reveals that the Ag NPs are uniformly immobilized in the Fe(3)O(4) microsphere-based supports. M...

Sumario:As hybrid nanostructures have become more important in many fields of chemistry, Ag nanoparticles (NPs) are being increasingly immobilized onto Fe(3)O(4) microspheres in situ. Structural characterization reveals that the Ag NPs are uniformly immobilized in the Fe(3)O(4) microsphere-based supports. Moreover, Ag NPs are more stable in the hybrid structure than in the naked state and show high catalytic activity for the reduction of nitro compounds and hydration of nitriles to amides in water. The Fe(3)O(4) microspheres were recycled several times using an external magnet.
