Catalysis is becoming a strategic field of science because it represents a new way to meet the challenges of energy and sustainability. The present work explores synthesis and catalytic activity of new magnetically recoverable ruthenium (Fe3O4@Ru) nanocatalysts by co-precipitation method in a single step. The synthesized magnetic Ru nanocatalysts are characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD), vibrating sample magnetometry (VSM), X-ray photoelectron spectroscopy (XPS) and atomic absorption spectrophotometry (AAS). As-prepared Fe3O4@Ru nanocatalysts have been applied for olefin hydrogenation reactions. The results indicate that the supported Ru catalysts can be conveniently recovered by applying an external magnetic field and the activity of the supported Ru catalyst for hydrogenation of olefins can still reach up to over 90% after being reused at least five times. Keywords: Fe3O4@Ru nanocatalysts, co-precipitation method, Characterization, Hydrogenation of olefins.
