Unexpected effects of trace impurities on the properties of polymer-stabilized ruthenium colloids from different sources of ruthenium(III) chloride hydrate
The stability and the catalytic performances of polyvinylpyrrolidone-stabilized ruthenium colloids (PVP-Ru) prepared by using RuCl3.xH(2)O of different sources have been investigated. The trace impurity content of platinum and palladium in RUCl3.xH(2)O was demonstrated to be the main factors affecting the properties of PVP-Ru colloids. (C) 2003 Elsevier Inc. All rights reserved.
