Polymer Stabilized

A series of well dispersed ruthenium nano-clusters using Polyvinylpyrrolidone (PVP) as stabilizer were synthesized by seed-mediated method. In this method, polymer-stabilized PVP-Ru nano-cluster with a diameter of about 3.14 nm was prepared by the reduction of RuCl3 in ethylene glycol and used as a seed solution (S), which was then added to the EG solution of ruthenium (Ⅲ) salts (E) to control the size of the Ru nano-cluster synthesized in this seed-mediated method. The influences of the amount of S solution that was added to E solution and the existence of PVP in ruthenium salts solution on the size of Ru were studied in this essay. Compared with the seed solution, the size of Ru nano-cluster increased with the decreasing of the amount of seed solution added. Moreover, the existence of PVP in the EG solution of ruthenium salts would hinder the Ru nano-cluster from growing since PVP will weaken the ability for newly formed Ru0 to regrow on the seed crystal.
