dc.description.abstractNanozirconia supported ruthenium(0) nanoparticles (Ru-0/ZrO2) were prepared by impregnation of ruthenium(III) cations on the surface of zirconia followed by their reduction with sodium borohydride at room temperature. Ru-0/ZrO2 was isolated from the reaction solution by centrifugation and characterized by ICP-OES, XRD, TEM, SEM EDS and XPS techniques. All the results reveal that ruthenium(0) nanoparticles were successfully supported on zirconia and the resulting Ru-0/ZrO2 is a highly active and reusable catalyst for hydrogen generation from the hydrolysis of ammonia borane with a turnover frequency value of 173 min(-1) at 25 degrees C. The reusability and catalytic lifetime tests reveal that Ru-0/ZrO2 is still active in the subsequent runs of hydrolysis of ammonia borane preserving 67% of the initial catalytic activity even after the fifth run and Ru-0/ZrO2 provides 72,500 turnovers (mol H-2/mol Ru) before deactivation at 25 degrees C. Our report also includes the results of kinetic studies depending on the catalyst concentration and temperature to determine the activation energy (E-a = 58 2 kJ/mol) for hydrolytic dehydrogenation of AB.
