In this paper, rGO/Pd–Fe3O4@PPy as an efficient stable nanocomposite was synthesized. To understand the synergetic effects of rGO, Pd, Fe3O4 and PolyPyrrole, the performance of rGO/Pd–Fe3O4@PPy as a heterogeneous recyclable nanocatalyst in the green synthesis of C‐C and C‐O coupling products, as well as different conditions are studied. Synthesized rGO/Pd–Fe3O4@PPy was characterized by FT‐IR, XRD,
在本文中,合成了rGO / Pd-Fe 3 O 4 @PPy作为一种有效的稳定纳米复合材料。要了解rGO ,Pd,Fe 3 O 4和聚吡咯的协同作用,rGO / Pd-Fe 3 O 4 @PPy作为C-C和C-O偶联产物绿色合成中的非均相可循环纳米催化剂的性能,以及不同条件的研究。FT-IR,XRD,FE-SEM,EDS,TGA和AFM分析表征了合成的rGO / Pd-Fe 3 O 4 @PPy。在H 2中超声处理可获得最佳结果O用于C‐C耦合,球磨用于C‐O耦合。该方法的优点包括:绿色溶剂和条件,无外部碱,反应时间短,产率高且易于加工。
