Synthesis of colloidal ruthenium nanocatalyst by chemical reduction method

Abstract

Colloidal ruthenium nanoparticles were prepared by chemical reduction of ruthenium trichloride (RuCl using sodium borohydrate (NaBH 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/RuCl NaBHRuCl 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-Alto prepare Ru/γ-Alcatalyst. This catalyst was characterized by X-ray Diffraction (XRD) and transmission electron microscope (TEM). © 2013 R. G.
