Palladium nanoparticle decorated on magnetic pomegranate peel-derived porous carbon nanocomposite as an excellent catalyst for cross-coupling reactions

The porous carbon (PC) material was prepared from the carbonization of pomegranate peel waste. Subsequently, the magnetically separable Fe3O4@PC was synthesized from the Fe3O4 nanoparticles decorated on PC by the co-precipitation method of iron ions. Finally, Fe3O4@PC was successfully decorated with palladium nanoparticles in a simple route by reducing H2PdCl4 in the presence of sodium dodecyl sulfate, which is used as both a surfactant and reducing agent. Additionally, the effect of temperature on carbonization process was studied. The Pd/Fe3O4@PC nanocomposite was used as an efficient and heterogeneous catalyst for the Suzuki-Miyaura and Sonogashira cross-coupling reactions in an environmentally friendly medium.
