Abstract

Alumina-supported Ru and Ru-Pt nanoparticles, obtained by the decarbonylation of organometallic cluster precursors, were found to be highly active and selective catalysts for ethanol steam reforming. These catalysts outperformed a commercial Ru/Al₂O₃ catalyst, as well as catalysts that had been prepared from inorganic salts using the conventional impregnation method. The highly dispersed nanoparticles derived from cluster precursors were much smaller than the salt-derived nanoparticles, as evidenced by TEM and powder XRD studies; this might account for the improved catalytic performance of the cluster-derived catalysts. Finally, EDX studies suggest that Pt played a role in resisting coke formation in both cluster- and salt-derived catalysts.
