Ruthenium(0) nanoparticles supported on zeolitic imidazolate framework (ZIF-8), RuNPs/ZIF-8, were reproducibly prepared by borohydride reduction of RuCl3/ZIF-(8) precatalyst in water at room temperature. The characterization of the dehydrated RuNPs/ZIF-8 was done by a combination of complimentary techniques, which reveals that the formation of well-dispersed ruthenium(0) nanoparticles (1.9 +/- 0.6 nm) on the surface of ZIF-8 by keeping the host framework intact. The catalytic activity of RuNPs/ZIF-8 was firstly tested in the dehydrogenation of dimethylamine-borane ((CH3)(2)NHBH3) in toluene. We found that ruthenium(0) nanoparticles supported on ZIF-8 can catalyze the dehydrogenation of dimethylamineborane with an initial TOF value of 59 min(-1) at 40 degrees C. Additionally, RuNPs/ZIF-8 catalyze the transfer hydrogenation of various unsaturated substrates in the presence of dimethylamine borane as hydrogen source even at low catalyst loadings. More importantly, they show high durability against leaching and sintering throughout the catalytic runs, which make them reusable catalyst in these important catalytic transformations.

Rhodium(0) nanoparticles supported on nanosilica: Highly active and long lived catalyst in hydrogen generation from the methanolysis of ammonia borane Ozhava, Derya; Özkar, Saim (Elsevier BV, 2016-02-01) Nanosilica stabilized rhodium(0) nanoparticles (Rh(0)/nanoSiO(2)), in situ formed from the reduction of rhodium(II) octanoate impregnated on the surface of nanosilica, are active catalyst in hydrogen generation from the methanolysis of ammonia borane at room temperature. Monitoring the hydrogen evolution enables us to follow the kinetics of nanoparticles formation. The resulting sigmoidal kinetic curves are analyzed by using the 2-step mechanism of the slow, continuous nucleation and autocatalytic surface g...
Nanoceria supported palladium(0) nanoparticles: Superb catalyst in dehydrogenation of formic acid at room temperature Akbayrak, Serdar; TONBUL, YALÇIN; Özkar, Saim (Elsevier BV, 2017-06-05) Highly efficient dehydrogenation of formic acid (FA) at room temperature was achieved using palladium(0) nanoparticles supported on nanoceria (Pd-0/CeO2) as catalysts. Pd-0/CeO2 was prepared by impregnation of palladium(II) ions on the surface of ceria followed by their reduction with sodium borohydride in aqueous solution at room temperature. Pd((0)/CeO2 was isolated from the reaction solution by centrifugation and characterized by a combination of advanced analytical techniques. The catalytic activity of ...
Palladium(0) nanoparticles supported on silica-coated cobalt ferrite: A highly active, magnetically isolable and reusable catalyst for hydrolytic dehydrogenation of ammonia borane Akbayrak, Serdar; KAYA, MURAT; Volkan, Mürvet; Özkar, Saim (Elsevier BV, 2014-04-05) Palladium(0) nanoparticles supported on silica-coated cobalt ferrite (Pd(0)/SiO2-CoFe2O4) were in situ generated during the hydrolysis of ammonia borane, isolated from the reaction solution by using a permanent magnet and characterized by ICP-OES, XRD, TEM, TEM-EDX, XPS and the N-2 adsorption-desorption techniques. All the results reveal that well dispersed palladium(0) nanoparticles were successfully supported on silica coated cobalt ferrite and the resulting Pd(0)/SiO2-CoFe2O4 are highly active, magnetica...
Ruthenium(0) nanoparticles supported on magnetic silica coated cobalt ferrite: Reusable catalyst in hydrogen generation from the hydrolysis of ammonia-borane Akbayrak, Serdar; KAYA, MURAT; Volkan, Mürvet; Özkar, Saim (Elsevier BV, 2014-11-15) Ruthenium(0) nanoparticles supported on magnetic silica-coated cobalt ferrite (Ru(0)/SiO2-CoFe2O4) were in situ generated from the reduction of Ru3+/SiO2-CoFe2O4 during the catalytic hydrolysis of ammonia-borane (AB). Ruthenium(III) ions were impregnated on SiO2-CoFe2O4 from the aqueous solution of ruthenium(III) chloride and then reduced by AB at room temperature yielding Ru(0)/SiO2-CoFe2O4 which were isolated from the reaction solution by using a permanent magnet and characterized by ICP-OES, XRD, TEM, TE...
Palladium(0) nanoparticles supported on polydopamine coated CoFe2O4 as highly active, magnetically isolable and reusable catalyst for hydrogen generation from the hydrolysis of ammonia borane Manna, Joydev; Akbayrak, Serdar; Özkar, Saim (Elsevier BV, 2017-07-05) Palladium(0) nanoparticles supported on cobalt ferrite (Pd degrees/CoFe2O4) are found to be highly active catalyst, providing an unprecedented catalytic activity with a turnover frequency of 290 min(-1) in hydrogen generation from the hydrolysis of ammonia borane at room temperature. However, the initial catalytic activity of Pd degrees/CoFe2O4 catalyst is not preserved after the reuse of the catalyst in hydrolytic dehydrogenation of ammonia borane. The stability of the catalyst is improved by using the pol...
