Here reported a facile approach to synthesize rattle type magnetic nanocomposite with a permeable Fe3O4 shell and noble metallic core. The core of yolk materials are controlled by varying the metallic ion precursor (such as K2PdCl4, AgNO3, KAuCl4, and Cu(NO3)(2)). The content of the metallic cores increases by increasing of the amount of the metallic salt. This one step method is based on an in situ reduction and Ostwald ripening process. As-obtained particles show porous nature and superparamagnetic characteristic. Moreover, the as-prepared magnetic recyclable nanocatalyst manifests high activity when evaluated for their catalytic properties and they can be separated from the reaction system by using a magnet.
