Catalytically active, low-cost, and reusable transition metal catalysts are desired to develop on-demand hydrogen generation system for practical onboard applications. Electrolessly deposited Pd-activated TiO2-supported Co-Ni-P ternary alloy catalyst (Co-Ni-P/Pd-TiO2) is employed as catalyst in the hydrolysis of alkaline sodium borohydride solution. The catalyst is found to be isolable, redispersible, and reusable in the hydrolysis of alkaline NaBH4. The reported work also includes the full experimental details for the collection of a wealth of kinetic data to determine the activation energy (E-a = 57.0 kJ/mol) and effects of the amount of catalyst, amount of substrate, and temperature on the rate for the catalytic hydrolysis of NaBH4. Maximum H-2 generation rate of similar to 460mLH(2) min(-1) (g catalyst)(-1) and similar to 3780mLH(2) min(-1) (g catalyst)(-1) was measured by the hydrolysis of NaBH4 at 25 degrees C and 55 degrees C respectively.

Hydrogen generation from the hydrolysis of ammonia borane using cobalt-nickel-phosphorus (Co-Ni-P) catalyst supported on Pd-activated TiO2 by electroless deposition
Rakap, Murat; Kalu, Egwu Eric; Özkar, Saim (Elsevier BV, 2011-01-01)
Catalytically active, low-cost, and reusable transition metal catalysts are desired to develop on-demand hydrogen generation system for practical onboard applications. By using electroless deposition method, we have prepared the Pd-activated TiO2-supported Co-Ni-P ternary alloy catalyst (Co-Ni-P/Pd-TiO2) that can effectively promote the hydrogen release from ammonia-borane aqueous solution. Co-Ni-P/Pd-TiO2 catalysts are stable enough to be isolated as solid materials and characterized by XRD, SEM, and EDX. ...
Catalytic hydrolysis of hydrazine borane for chemical hydrogen storage: Highly efficient and fast hydrogen generation system at room temperature
Karahan, Senem; Zahmakiran, Mehmet; Özkar, Saim (2011-04-01)
There has been rapidly growing interest for materials suitable to store hydrogen in solid state for transportation of hydrogen that requires materials with high volumetric and gravimetric storage capacity. B-N compounds such as ammonia-triborane, ammonia-borane and amine-borane adducts are well suited for this purpose due to their light weight, high gravimetric hydrogen storage capacity and inclination for bearing protic (N-H) and hydridic (B-H) hydrogens. In addition to them, more recent study [261 has sho...
Cobalt Oxide Nanoflakes on Single Walled Carbon Nanotube Thin Films for Supercapacitor Electrodes
Durukan, Mete Batuhan; Ünalan, Hüsnü Emrah (2016-12-20)
We demonstrate a simple and cost-effective approach for the fabrication of cobalt oxide (Co3O4) nanoflakes on single walled carbon nanotube (SWNT) thin films for supercapacitor electrodes. SWNT thin films are prepared by vacuum filtration and consecutive stamping method onto which cobalt hydroxide (Co(OH)(2)) nanoflakes are electrodeposited and annealed to obtain Co3O4. A gravimetric capacitance of 313.9 F.g(-1), corresponding to an areal specific capacitance of 70.5 mF.cm(-2) is obtained from the fabricate...
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...
Synthesizing germanium and silicon nanocrystals embedded in silicon dioxide by magnetron sputtering technique
Alagöz, Arif Sinan; Turan, Raşit; Department of Physics (2007)
Applications of semiconductor nanocrystal in electronics are promising. Various techniques were developed to synthesize and analyze semiconductor nanocrystals for integrated circuit applications. In this study, silicon and germanium nanocrystals were synthesized in silicon dioxide matrix by magnetron sputtering deposition and following high temperature furnace annealing. Multilayer and single layer samples were prepared by co-sputtering depositions. Transmission electron microscopy measurements were carried...
