Graphene oxide: preparation, functionalization, and electrochemical applications.

Surface functionalization of nano-magnetic nanoparticles is a well-designed way to bridge the gap between heterogeneous and homogeneous catalysis. The introduction of magnetic nanoparticles (MNPs) in a variety of solid matrices allows the combination of well-known procedures for catalyst heterogenization with techniques for magnetic separation. Magnetite is a well-known material, also known as ferrite (Fe3O4), and can be used as a versatile support for functionalization of metals, organocatalysts, N-heterocyclic carbenes, and chiral catalysts. It is used as a support for important homogeneous catalytically active metals such as Pd, Pt, Cu, Ni, Co, Ir, etc. to obtain stable and magnetically recyclable heterogeneous catalysts. Homogeneous organocatalysts can be successfully decorated with linkers/ligands on the surface of magnetite or alternatively the organocatalysts can be directly immobilized on the surface of magnetite. The functionalized magnetically retrievable catalysts or nanocatalysts that are increasingly being used in catalysis, green chemistry and pharmaceutically significant reactions are summarized in this review.

Pd immobilized on amine-functionalized magnetite nanoparticles: a novel and highly active catalyst for hydrogenation and Heck reactions

Stabilizing Pd on the surface of hollow magnetic mesoporous spheres: a highly active and recyclable catalyst for hydrogenation and Suzuki coupling reactions

A novel magnetically recoverable Pt nanoparticle catalyst was prepared by in situ NaBH4 reduction of a Pt4+ species bound to hydroxyl modified carbon-coated magnetic microparticles. The prepared ‘green’ catalyst allows for rapid and effective hydrogenation of aromatic nitro-compounds with excellent product yields as well as easy catalyst separation and recovery.
