Abstract
This chapter provides an overview on supported metal nanoparticles (NPs) on magnetic nanomaterials and their applicability in heterogeneous catalysis. Metal NPs have been successfully immobilized on polymers, membranes, mesoporous silica, and solid supports. The immobilization of metal NPs on magnetic nanomaterials has taken great interest, due to their nanometric size, which increases their surface area. In addition, the magnetic NPs (MNPs) can be easily separated from the reaction medium, by applying an external magnetic field. The support of various MNPs has been mainly investigated using two different magnetic supports: cobalt ferrite CoFe2O4 and magnetite Fe3O4. Magnetoresponsive polymeric beads have been investigated intensively in the last decade due to their potential applications in a wide range of fields. Mostly, two kinds of magnetic polymeric beads have been used for supporting metal NPs. One is based on beads with core-shell structure and a second kind related to composite nano- or microspheres.
