Previously being used as highly active catalyst in the hydrolysis of sodium borohydride, intrazeolite cobalt(0) nanoclusters were also employed as catalyst in the hydrolysis of ammonia-borane (H(3)NBH(3)). Intrazeolite cobalt(0) nanoclusters were found to be active catalyst in this hydrolysis reaction of ammonia-borane providing 5450 total turnovers at room temperature before deactivation. The results of the kinetic study shows that the catalytic hydrolysis of AB is first order with respect to the catalyst concentration and zero order with respect to substrate concentration. Activation parameters could be obtained from the evaluation of the rate constants at different temperature. The results reveal that intrazeolite cobalt(0) nanoclusters can be considered as promising candidate to be used as catalyst in developing highly efficient portable hydrogen generation systems using ammonia-borane as solid hydrogen storage material.

Hydrogen generation from the hydrolysis of hydrazine-borane catalyzed by rhodium(0) nanoparticles supported on hydroxyapatite Celik, Derya; Karahan, Senem; Zahmakiran, Mehmet; Özkar, Saim (2012-03-01) Herein, we report the preparation and characterization of rhodium(0) nanoparticles supported on hydroxyapatite (Ca-10(OH)(2)(PO4)(6), HAP) and their catalytic use in the hydrolysis of hydrazine-borane, which attracts recent attention as promising hydrogen storage materials. Hydroxyapatite supported rhodium(0) nanoparticles were readily prepared by the hydrazine-borane reduction of rhodium(III)-exchanged hydroxyapatite in situ during the hydrolysis of hydrazine-borane at room temperature. Characterization of...
Hydroxyapatite-supported cobalt(0) nanoclusters as efficient and cost-effective catalyst for hydrogen generation from the hydrolysis of both sodium borohydride and ammonia-borane Rakap, Murat; Özkar, Saim (2012-03-20) Herein, we report the preparation, characterization, and catalytic use of cobalt(0) nanoclusters supported on hydroxyapatite in the hydrolysis of both basic sodium borohydride and ammonia-borane solutions. They were prepared in situ from the reduction of cobalt(II) ions adsorbed on hydroxyapatite with sodium borohydride. Hydroxyapatite-supported cobalt(0) nanoclusters were stable enough to be isolated as solid material and characterized by inductively coupled plasma optical emission spectroscopy (ICP-OES), ...
Hydrogen generation from the methanolysis of ammonia borane catalyzed by in situ generated, polymer stabilized ruthenium(0) nanoclusters Erdogan, Huriye; Metin, Onder; Özkar, Saim (2011-07-19) Addressed herein is the detailed study on in situ generation of poly(N-vinyl-2-pyrrolidone) (PVP) stabilized ruthenium(0) nanoclusters and their catalysis in the methanolysis of ammonia borane (AB). PVP-stabilized ruthenium(0) nanoclusters with an average particle size of 2.4 +/- 1.2 nm were generated in situ from the reduction of ruthenium(III) chloride during the methanolysis of AB in the presence of PVP at room temperature. The nanoclusters were characterized by UV-vis spectroscopy, TEM, XRD, XPS and FTI...
Palladium(0) nanoparticles supported on ceria: Highly active and reusable catalyst in hydrogen generation from the hydrolysis of ammonia borane Tonbul, Yalcin; Akbayrak, Serdar; Özkar, Saim (2016-07-13) Palladium(0) nanoparticles supported on nanoceria (Pd-0/CeO2) were prepared by the 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 were isolated from the reaction solution by centrifugation and characterized by ICP-OES, XRD, TEM, SEM-EDS and XPS techniques. All the results reveal that palladium(0) nanoparticles were uniformly dispersed on ceria and the resulting Pd-0/CeO2 are highly active and r...
Cobalt ferrite supported platinum nanoparticles: Superb catalytic activity and outstanding reusability in hydrogen generation from the hydrolysis of ammonia borane Akbayrak, Serdar; Özkar, Saim (2021-08-15) In this work, platinum(0) nanoparticles are deposited on the surface of magnetic cobalt ferrite forming magnetically separable Pt-0/CoFe2O4 nanoparticles, which are efficient catalysts in H-2 generation from the hydrolysis of ammonia borane. Catalytic activity of Pt-0/CoFe2O4 nanoparticles decreases with the increasing platinum loading, parallel to the average particle size. Pt-0/CoFe2O4 (0.23% wt. Pt) nanoparticles have an average diameter of 2.30 +/- 0.47 nm and show an extraordinary turnover frequency of...
