Abstract

Stable iron, ruthenium, and osmium nanoparticles are obtained reproducibly by thermal or photolytic decomposition under an argon atmosphere from Fe2(CO)9, Ru3(CO)12, and Os3(CO)12, dissolved in the ionic liquid BMim+BF4−, with a very small and uniform size for Ru and Os nanoparticles of about 1.5−2.5 nm without any additional stabilizers or capping molecules (characterization by transmission electron microscopy (TEM), dynamic light scattering, and transmission electron diffraction (TED) analysis).
