Colloidal ruthenium nanoparticles were prepared by chemical reduction of ruthenium trichloride RuCl3 using sodium borohydrate NaBH4 as reducing agent and sodium dodecyl sulfate SDS as a stabilizer. Size and size distribution of synthesized colloidal Ru nanoparticles were studied by varying different parameters such as molar ratio MR of SDS-RuCl3, NaBH4-RuCl3, effects of different stabilizers, and reducing agents. Prepared nanoparticles were characterized by transmission electron microscope TEM and dynamic light scattering DLS. Stability of colloidal nanoparticles was detected by Turbiscan. Stable Ru nanoparticles were dispersed on γ-Al2O3 to prepare Ru-γ-Al2O3 catalyst. This catalyst was characterized by X-ray Diffraction XRD and transmission electron microscope TEM.
