RAMIREZ-MENESES, Esther; PHILIPPOT, Karine  e  CHAUDRET, Bruno. Influence of the Reaction Media on the Stabilization of Rhodium Nanostructures. Ing. invest. y tecnol. [online]. 2015, vol.16, n.2, pp.225-237. ISSN 2594-0732.

Rh nanostructures were synthesized from [Rh(acac)(1,5-C₈H₁₂)] under hydrogen atmosphere (3 bar) in organic media with the aim to study the effect of ligands concentration in the reaction media (composed by acetylacetonate, 1,5-cyclooctadiene and 2,4-pentanediol) on the stabilization of the obtained nanostructures. Moreover, the effect of the addition of classic stabilizers such as polyvinylpyrrolidone (PVP) and hexadecylamine (HDA) was also studied. Finally, the obtained Rh nanostructures were characterized by Transmission Electron Microscopy (TEM).
