Abstract: Alcohothermal process for the preparation of metallic Ru nanoparticles in the ethanol solution is described. The solvothermal reaction shows different colors during the heat treatment at 120 ℃ at different reaction times. Monodispersed ruthenium colloidal nanoparticles with a diameter of 3-6 nm in the ethanol solution were obtained by adding acetate ions as a stabilization reagent. Ru powders composed of 1-5 nm particles capped by hexadecyltrimethylammonium bromide (HTAB) were also synthesized by this method.
Key words: ruthenium; alcohothermal; nanoparticles
