Abstract
Fe3O4@SiO2-APTES-Pt was prepared from 3-aminopropyl triethoxysilane via immobilization on Fe3O4@SiO2, followed by reacted with chloroplatinic acid. The obtained catalyst was characterized by XRD, TEM, FT-IR, XPS and ICP-AES. This catalyst showed extraordinary catalytic performances for hydrosilylation of olefins with triethoxysilane. It was recovered from the reaction medium just by sequestering by a magnet and then reused several times without significant loss in catalytic activity and selectivity.
