Abstract
Ruthenium trichloride precursor and Poly (N-vinyl-2-pyrrolidone) (PVP as a stabilising agent) were dissolved in ethylene glycol which played as a solvent and as well as reducing agent. Microwave irradiation (MWI) was applied for the in situ activation of the reaction to reduce Ru3+ to Ru(0). Agglomerations of Ruthenium nanoparticles (metallic Ru) were restricted by using excess solvent and stabilizer (PVP). Nanoparticles were characterized by UV-Vis spectroscopy, Particle Size Analyzer and Transmission electron microscopy (TEM) etc. The influences of different parameters like PVP/RuCl3 molar ratio (0.6–1) and microwave irradiation power (100–300 W) on the size and size distribution had been systematically investigated. Monodisperse, well-shaped ruthenium nanoparticles in the range of 4–20 nm with narrow size distribution (average diameter 14 nm) were synthesized using optimized reaction parameters.
