Ceria-supported ruthenium nanoparticles as highly active and long-lived catalysts in hydrogen generation from the hydrolysis of ammonia borane
Ruthenium(0) nanoparticles supported on ceria (Ru 0 /CeO 2 ) were in situ generated from the reduction of ruthenium( iii ) ions impregnated on ceria during the hydrolysis of ammonia borane. Ru 0 /CeO 2 was isolated from the reaction solution by centrifugation and characterized by ICP-OES, BET, XRD,...

provides a superior catalytic lifetime (TTO = 135 100) in hydrogen generation from the hydrolysis of ammonia borane at 25.0 ± 0.1 °C before deactivation. The work reported here includes the formation kinetics of ruthenium(0) nanoparticles. The rate constants for the slow nucleation and autocatalytic surface growth of ruthenium(0) nanoparticles were obtained using hydrogen evolution as a reporter reaction. An evaluation of rate constants at various temperatures enabled the estimation of activation energies for both the reactions,
