Dimethylamine-borane, (CH3)(2)NHBH3, has been considered as one of the attractive materials for the efficient storage of hydrogen, which is still one of the key issues in the "Hydrogen Economy". In a recent communication we have reported the synthesis and characterization of 3-aminopropyltriethoxysilane stabilized ruthenium(0) nanoparticles with the preliminary results for their catalytic performance in the dehydrogenation of dimethylamine-borane at room temperature. Herein, we report a complete work including (i) effect of initial [APTS]/[Ru] molar ratio on both the size and the catalytic activity of ruthenium(0) nanoparticles, (ii) collection of extensive kinetic data under non-MTL conditions depending on the substrate and catalyst concentrations to define the rate law of Ru(0)/APTS-catalyzed dehydrogenation of dimethylamine-borane at room temperature, (iii) determination of activation parameters (E-a, Delta H# and Delta S#) for Ru(0)/APTS-catalyzed dehydrogenation of dimethylamine-borane; (iv) demonstration of the catalytic lifetime of Ru(0)/APTS nanoparticles in the dehydrogenation of dimethylamine-borane at room temperature, (v) testing the bottlability and reusability of Ru(0)/APTS nanocatalyst in the room-temperature dehydrogenation of dimethylamine-borane, (vi) quantitative carbon disulfide (CS2) poisoning experiments to find a corrected TTO and TOF values on a per-active-ruthenium-atom basis, (vii) a summary of extensive literature review for the catalysts tested in the catalytic dehydrogenation of dimethylamine-borane as part of the results and discussions.

Long-term stable hydrogen production from acetate using immobilized Rhodobacter capsulatus in a panel photobioreactor
Elkahlout, Kamal; Sagir, Emrah; Alipour, Siamak; Koku, Harun; Gündüz, Ufuk; Eroglu, Inci; Yucel, Meral (2019-07-12)
Biological hydrogen production is attractive since renewable resources are utilized for hydrogen production. In this study, a novel panel photobioreactor (1.4 L) was constructed from Plexiglas with a network of nylon fabric support for agar immobilized bacteria complex. Two strains of Rhodobacter capsulatus DSM 1710 wild-type strain and Rhodobacter capsulatus YO3 (hup(-), uptake hydrogenase deleted mutant) with cell concentrations of 2.5 and 5.0 mg dcw/mL agar, respectively were entrapped by 4% (w/v) of aga...
CaXH3 (X = Mn, Fe, Co) perovskite-type hydrides for hydrogen storage applications
SÜRÜCÜ, GÖKHAN; Gencer, Ayşenur; Candan, Abdullah; Güllü, Hasan Hüseyin; IŞIK, MEHMET (Wiley, 2019-12-12)
Hydrogen storage is one of the attractive research interests in recent years due to the advantages of hydrogen to be used as energy source. The studies on hydrogen storage applications focus mainly on investigation of hydrogen storage capabilities of newly introduced compounds. The present paper aims at characterization of CaXH3 (X: Mn, Fe, or Co) perovskite-type hydrides for the first time to understand their potential contribution to the hydrogen storage applications. CaXH3 compounds have been investigate...
First principles investigation of hydrogen storage in intermetallic systems
Kınacı, Alper; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2007)
The design and production of efficient metal-hydrides for hydrogen storage is a long standing subject. Over the years, many different types of intermetallic hydride systems were studied and some of them came out to be operable. However, none of them meet all the storage criteria perfectly. In this study, total energies, hydrogen storage capacity and stability of AB (A = Al, Be, Cu, Fe, Ni, Sb, V and B = Ti) type intermetallics were investigated with the goal of spotting a potential hydrogen storage material...
Long term outdoor testing of two different thin film pv modules in Ankara Turkey
Özden, Talat; Akınoğlu, Bülent Gültekin; Turan, Raşit (null; 2016-09-21)
Degradation of photovoltaic (PV) cells and modules in the long term is very important in transition to new energy policies by using renewables. Thin film solar cells are used commercially almost worldwide. In this context, we tested two different solar PV modules of copper indium gallium selenide and amorphous silicon thin film for four years. We used anisotropic sky model to calculate the solar irradiation input to the tilted modules and reached monthly performances, namely the efficiency and performance r...
Application of density functional theory to propylene to propylene oxide catalytic reaction
Onay, Deniz; Önal, Işık; Fellah, Mehmet Ferdi; Department of Chemical Engineering (2015)
Current propylene oxide production highly relies on costly and environmentally disadvantageous processes. Direct propylene epoxidation on heterogeneous surface is desired to replace these processes. With this ultimate goal in mind, propylene epoxidation has been investigated on Cu2O(001) and RuO2(110) surfaces. Different elementary steps of the reaction mechanism that result in propylene oxide formation are analyzed on these catalytic models by using Density Functional Theory (DFT) calculations via Vienna A...
