23 - Magnetic hybrid nanocatalysts

Abstract

Magnetic nanoparticles (NPs) in both individual and composite forms are substantial tools for catalytic purposes because they provide an extreme surface area through their nanoscale diameter. Recently, this species of nanomaterials has attracted much attentions in catalysis of the organic and inorganic reactions because the separation and purification processes can be easily performed by applying them. In addition, they can be recycled and reused for several successive cycles, which is a considerable advantage. Briefly, after completion of the synthetic reactions, the magnetic particles can be collected by holding an external magnet at the bottom of the flask, and the purification process is carried out by decanting of the rest mixture. The collected particles can be dried, reactivated, and reused if they are physically stable enough. In this chapter we will highlight the advantages of the use of the magnetic NPs in hybrid forms, which have recently been utilized in catalytic applications.
