Abstract

Abstract In this paper, a new magnetic hybrid nanomaterial (Fe 3 O 4 @SiO 2 @PPh 3 @[CrO 3 Cl]) was reported for the first time. The magnetic Fe 3 O 4 nanoparticles were prepared by hydrothermal process and coated with a silica shell. Then, the core–shell nanoparticles (Fe 3 O 4 @SiO 2 ) were functionalized by 3-chloropropyl trimethoxysilane plus triphenylphosphine for forming the cationic part of support. Finally, anionic part of the Cr(VI) catalyst ([CrO 3 Cl] − ) was immobilized on the magnetic support (Fe 3 O 4 @SiO 2 @PPh 3 ). The structural characteristics of the product were determined using elemental analysis, X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) and solid state UV–Vis. The particle size and morphology were identified by scanning electron microscope (SEM), transmission electron microscopy (TEM) and XRD. A vibrant sample was employed to determine the magnetic properties of the prepared samples.
