In a simple approach, gold was successfully anchored to the surface of thiol-functionalized super paramagnetic Fe3O4 nanoparticles as heterogeneous catalyst. The core/shell Fe3O4@SiO2@SiO2-SH-Au was prepared in a facile procedure, without using any reducing reagents by in situ reduction of Au3+. The catalyst was characterized by TEM, SEM, IR, XRD and EDX. The catalyst with loaded iron oxide nanoparticles...
