摘要：

Immobilization of Pd(II) nanoparticles on silica-coated modified magnetite particles has been readily achieved via a surface modification of Fe3O4 particles with 4-amino-5-methyl-4-H-1,2,4-triazole-3-thiol (4-AMTT) as a ligand. This magnetite nanocatalyst was characterized by various analyses such as FT-IR, SEM/EDX, ICP-AES, VSM, TEM, XRD, XPS and TGA. This nanocatalyst showed admirable catalytic activity for Suzuki-Miyaura and Mizoroki-Heck cross-coupling reactions under mild conditions in water, and could be simply separated by an outer magnet and reused for several times.
