New Pd(Pt) catalysts have been fabricated by assembling multicomponents of Fe3O4 and CeO2/Pd(Pt) on the surface of reduced graphene oxide (RGO) nanosheets in layers. The as-obtained Pd(Pt) catalysts exhibit extremely high catalytic activity in the selective hydrogenation reaction of nitrobenzene. Owing to the presence of Fe3O4, the catalysts can be easily recycled from the catalytic system through magnetic separation. Their high activity, stability, and magnetic recyclability make the as-obtained hybrids very promising as catalysts in catalytic applications. Compared to other traditional multishell magnetic catalysts that were prepared by means of layer-by-layer technology, our process is much more facile and more easily controlled.
已通过在还原氧化石墨烯 (RGO) 纳米片表面层组装 Fe3O4 和 CeO2/Pd(Pt) 等多种成分来制备新型 Pd(Pt) 催化剂。所获得的 Pd(Pt) 催化剂在硝基苯的选择性加氢反应中表现出极高的催化活性。由于存在 Fe3O4，催化剂可以通过磁分离从催化体系中轻松回收。它们的高活性、稳定性和磁性可回收性使所获得的混合物非常有前途，可作为催化应用中的催化剂。与通过层层技术制备的其他传统多壳磁性催化剂相比，我们的工艺更加简单，更容易控制。
