Abstract	The simple preparation of catalysts with superior catalytic activity and good reusability is highly desirable. Herein, we report a novel strategy to construct reduced graphene oxide $(rGO)/Pd–Fe_{3}O_{4}@polypyrrole$ (PPy) catalysts with Pd and $Fe_{3}O_{4}$ nanoparticles anchored on a rGO nanosheet surface and wrapped in a PPy shell. The synthesis and assembly of both the Pd and $Fe_{3}O_{4}$ nanoparticles, the preparation of the PPy layer, and the reduction of graphene oxide nanosheets were finished in one step. In the system, the PPy layer not only prevented aggregation of Pd and $Fe_{3}O_{4}$ nanoparticles, but also generated a synergistic effect with precursor $Pd^{2+}$ ions, which led to a high dispersity of as-prepared Pd nanoparticles. Although the procedure was simplified to one step, the catalytic activity and reusability were not sacrificed. In the reduction of 4-nitrophenol, their catalytic performance was better than that in recent reports. Moreover, the catalysts showed good reusability owing to their magnetic properties.
