Green chemistry, also called sustainable chemistry, is a philosophy of chemical research and engineering that encourages the design of products and processes that minimize the use and generation of hazardous substances. Green catalysis is a subchapter of green chemistry and probably the most important one. We here report the synthesis, characterization and catalytic performance of recoverable ruthenium (Ru) supported on silica coated magnetic microspheres (Fe3O4@SiO2@Ru). The immobilized Ru nanoparticles catalyst (Fe3O4@SiO2@Ru) was obtained after reduction of Ru3+ on the amine-modified core?shell magnetic Fe3O4@SiO2 microspheres. As-prepared Ru catalysts were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), powder X-ray diffraction (XRD) and Fourier Transform Infra Red (FT-IR) spectroscopy. The synthesized Ru catalyst was successfully applied for organic catalytic reactions. The central Fe3O4 cores are superparamagnetic at room temperature with strong magnetic response to externally applied magnetic field, thus providing a convenient means for separating the catalyst from solution. Keywords: Green synthesis, Fe3O4@SiO2 microspheres, Ru nanoparticles, Catalytic applications.
