Abstract

Disclosed are ruthenium nanoparticles having an essentially face-centered cubic structure. Disclosed is a method for producing ruthenium nanoparticles having an essentially face-centered cubic structure. This production method includes a step (i) of maintaining a solution containing ruthenium (III) acetylacetonate, polyvinylpyrrolidone, and triethylene glycol at a temperature of 180° C. or higher.
