Iron Nanoparticles Supported on Chemically‐Derived Graphene: Catalytic Hydrogenation with Magnetic Catalyst Separation

Abstract

Iron nanoparticles (Fe-NP) supported on chemically-derived graphene (CDG) were prepared and identified as an effective catalyst for the hydrogenation of alkenes and alkynes. The catalyst can easily be separated by magnetic decantation.

Versatilities of graphene-based catalysts in organic transformations

“…Nevertheless, the complete conversion (100%) was achieved by adding a small amount of Grignard reagent (GR), ethyl magnesium chloride (EtMgCl; Scheme 27). 95 It was supposed that GR acts as a surface activator and reduces remaining oxide shells of the FeNPs, which may form via remaining oxide functions on CDG. The catalyst was separated elegantly by simple magnetic decantation and recycled without loss of activity.…”

Nanocatalysts for Hydrogenation Reactions

“…Fe-NPs supported on chemically derived graphene have been used as catalysts for catalytic hydrogenation and magnetic catalyst separation. 9 These catalysts were found to be effective for the hydrogenation of alkenes and alkynes. The authors have developed a simple, cheap, and rapid synthesis of Fe-NPs supported on chemically derived graphene.…”

“…This will lead to an improvement in electrical conductivity [5]. Magnetic nanomaterials have also attracted a lot of interest of scientists recently owing to their practical and potential applications, such as biomacromolecule separation, catalyst separation, drug/gene delivery and release, and magnetic resonance imaging [6][7][8].…”
