The design and preparation of recyclable catalysts are of great economic and environmental importance in the chemical and medicinal industries. Immobilization of homogeneous catalysts on various insoluble supports can lead to simplified catalyst recycling by filtration or centrifugation. Nanoparticles (NPs) are attractive candidates as solid supports for the immobilization of homogeneous catalysts and because of their large surface area, which can bear a large amount of catalytically active species, these supported catalysts display very high activity under mild conditions. Among these NPs, much attention has been directed toward the production of magnetic nanoparticles (MNPs), because these NPs can be well dispersed in reaction mixtures without magnetic field thus providing large surface for ready access to substrate molecules.
