Core–Satellite Heterostruture of Fe3O4–Pd Nanocomposite: Selective and Magnetically Recyclable Catalyst for Decarboxylative Coupling Reaction in Aqueous Media

Fe 3 O 4 -Pd nanocomposite having core-satellite heterostructure, prepared through the reaction of Pluronic polymer (P123, PEO 19 -PPO 69 -PEO 19 )-coated Fe 3 O 4 nanoparticle and Na 2 PdCl 4 , showed high catalytic activity, selectivity, and reusability for decarboxylative coupling reactions in aqueous media.
