摘要
Carbon encapsulated Au@Fe nanoparticles (NPs) were synthesized by the hydrothermal method, and the palladium NPs (12 nm) were immobilized on this hydroxyl-terminated support. The morphology, composition, content and magnetism of the samples were characterized. Compared with the commercial carbon-supported Pd catalyst, high catalytic activity, recyclability and selectivity were evaluated by the catalyst Pd/(C@(Au@Fe)) in the Heck reaction. Especially, in the Heck cross-coupling reactions of iodobenzene and methyl acrylate, the catalyst was reused 10 times without significant loss of activity. In addition, the catalyst was simply recycled by a magnetic field.
