摘要：
Pd-Fe3O4@C hybrid nanoparticles with 10 nm Pd nanocrystals deposited on the surface of 120 nm Fe3O4@C core-shell nanospheres have been prepared by the adsorption Pd2+ ions onto the surface of Fe3O4@C nanospheres with highly negative charges and followed by reduction of Pd2+ ions with ethanol at 60 degrees C. The heterodimer nanocrystals were completely recoverable under an external magnetic field, reused 10 times, and showed excellent activity in various Suzuki coupling reactions at room temperature.
