Hydrothermal synthesis and physicochemical properties of ruthenium(0) nanoparticles

The synthesis of ruthenium nanoparticles in hydrothermal conditions using mild reducing agents (succinic acid, ascorbic acid and sodium citrate) is reported. The shape of the nanoparticles depends on the type of the reducing agent, while the size is more influenced by the pH of the medium. The magnetic response seems to be dominated by a paramagnetic contribution characteristic of the band electronic magnetism of the nanoparticles.

► Ruthenium nanoparticles were synthesized by hydrothermal technique.
► The average size of the nanoparticles are depend on the reducing agent used.
► The magnetic response seems to be dominated by a paramagnetic contribution characteristic of the band electronic magnetism of the ruthenium(0) nanoparticles.
