Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Ruthenium (III) chloride salt and Poly (N‐vinyl‐2‐pyrrolidone) (PVP as a capping agent) was dissolved in ethylene glycol, which played a dual role for synthesis, as solvent and also as reducing agent. Microwave (MW) irradiation was applied to the solvent which provided controllable thermal activation for synthesis of ruthenium nanoparticles and also restricted the agglomeration of particles in presence of excess amount of solvent, which was recovered by distillation after completion of reaction. Synthesized particle was found to be in the range of 2–20 nm with narrow size distribution and average particle size was around 14 nm. Particle size and size distribution were studied by varying different parameters e.g. reaction temperature, time, PVP/RuCl₃ molar ratio and irradiation power and was characterized by Transmission electron microscopy (TEM). Mathematical model has been developed using matlab software to obtain the particle size as a function of microwave power.</p> </abstract>
