| This research concerns the synthesis of well-defined RuO2 nanocrystals. Our hypothesis is RuO2 nanoparticles can be synthesized by oxidation of ruthenium (Ru) nanoparticles with retention of size and shape. Ru nanoparticles were prepared from the decomposition of triruthenium(0)dodecacarbonyl (Ru3(CO)12) or ruthenium(III) trichloride trihydrate (RuCl3.3H2O) in the presence of surfactant, oxidant, and solvent at high temperature. The stabilized nanocrystals were isolated by centrifugation and characterized with transmission electron microscopy (TEM). RuO2 was synthesized by addition Ru nanocrystals and an oxygen atom source to a high temperature solution containing a molecular surfactant. TEM, powder X-ray diffraction, and Raman spectroscopy were used to characterize RuO2 nanoparticles. |
