Abstract:	Positively charged ruthenium nanoparticles were prepared by NaBH 4 reduction at room temperature and at pH values lower than 4.9. The ruthenium nanoparticles were characterized by zeta potential measurement, TEM, XPS, and XRD. Particles with a mean diameter of 1.8 nm and a standard deviation of 0.40 nm could be obtained under the experimental conditions. The surface charge on the particles is believed to originate from hydrated proton adsorption. The positively charged ruthenium nanoparticles could be used as the starting material for further functionalization by PVP, ethylenediamine, and dodecylamine. © 2003 Elsevier Inc.
