A new palladium(0) nanocatalyst is developed to enhance the catalytic efficiency of precious metal catalysts in hydrogen generation from the hydrolytic dehydrogenation of ammonia borane. Magnetically separable Pd-0/Co3O4 nanocatalyst can readily be obtained by the reduction of palladium(II) cations impregnated on cobalt(II, III) oxide at room temperature. The obtained Pd-0/Co3O4 nanocatalyst with 0.25% wt. palladium loading has outstanding catalytic activity with a record turnover frequency of 3048 min(-1) in the releasing H-2 from the hydrolysis of ammonia borane at 25.0 degrees C. They also provide out-standing reusability even after the tenth run of the hydrolysis of ammonia borane at 25.0 degrees. The high activity and superb stability of magnetically isolable Pd-0/Co3O4 nanoparticles are attributed to the favor-able interaction of palladium with the surface of reducible cobalt oxide.

Palladium(0) nanoparticles supported on polydopamine coated Fe3O4 as magnetically isolable, highly active and reusable catalysts for hydrolytic dehydrogenation of ammonia borane
Manna, Joydev; Akbayrak, Serdar; Özkar, Saim (2016-01-01)
Magnetic ferrite nanopowders were coated with polydopamine which is inert against the hydrolysis of ammonia borane. Coating of ferrite powders was achieved by pH-induced self-polymerization of dopamine hydrochloride at room temperature. Palladium(0) nanoparticles supported on polydopamine coated ferrite (Pd-0/PDA-Fe3O4) were prepared by impregnation of palladium(II) ions on the surface of PDA-Fe3O4 followed by their reduction with sodium borohydride in aqueous solution at room temperature. Magnetically isol...
Palladium nanoparticles supported on chemically derived graphene: An efficient and reusable catalyst for the dehydrogenation of ammonia borane
Metin, Onder; Kayhan, Emine; Özkar, Saim; Schneider, Jorg J. (2012-05-01)
Chemically derived graphene (CDG) was prepared by hydrazine hydrate reduction of graphene oxide and used as support for palladium nanoparticles (Pd NPs) generated ex situ with controllable particle size and dispersion. The Pd NPs supported on CDG were well characterized by using a combination of advance analytical techniques and employed as catalyst in the dehydrogenation and hydrolysis of ammonia borane (AB) in organic solvents and aqueous solutions, respectively. Monodisperse Pd NPs of 4.5 nm were prepare...

Herein, we report the in situ generation, isolation and characterization of cobalt(0) nanoparticles, stabilized by poly(4-styrenesulfonic acid-co-maleic acid), PSSMA, and their catalytic activity in the hydrolysis of hydrazine borane (HB). Cobalt(0) nanoparticles having average particle size of 3.1 +/- 0.5 nm were prepared by in situ reduction of cobalt(II) chloride in aqueous solution of hydrazine borane in the presence of PSSMA, isolated magnetically from the catalytic reaction solution using a magnet, an...
Hydrolytic dehydrogenation of ammonia borane catalyzed by reduced graphene oxide supported monodisperse palladium nanoparticles: High activity and detailed reaction kinetics
Kilic, Buket; Sencanli, Selin; Metin, Onder (2012-09-01)
A highly active and stable catalyst for the hydrolytic dehydrogenation of ammonia borane (AB) was prepared by supporting monodisperse palladium nanoparticles (Pd NPs) on reduced graphene oxide (RGO) via a facile method. RGO was prepared via modified chemical route and used as support matrices for monodisperse Pd NPs that were formed by the reduction of palladium(II) acetylacetonate by borane tert-butylamine complex in the presence of oleylamine. RGO supported Pd NPs (RGO@Pd) show high activity and stability...
Nanoalumina-supported rhodium(0) nanoparticles as catalyst in hydrogen generation from the methanolysis of ammonia borane
Ozhava, Derya; Özkar, Saim (2017-10-01)
Rhodium(0) nanoparticles were in situ formed from the reduction of rhodium(II) octanoate and supported on the surface of nanoalumina yielding Rh(0)/nanoAl(2)O(3) which is highly active catalyst in hydrogen generation from the methanolysis of ammonia borane at room temperature. The kinetics of nanoparticle formation can be followed just by monitoring the volume of hydrogen gas evolved from the methanolysis of ammonia borane. The evaluation of the kinetic data gives valuable insights to the slow, continuous n...
