Herein we report, for the first time, the preparation and characterization of water soluble rhodium(0) nanoclusters stabilized by laurate (dodecanoate) anion and their catalytic activity in the hydrolysis of ammonia-borane. The water soluble laurate-stabilized rhodium(0) nanoclusters were prepared from the reduction of rhodium(III) chloride by dimethylamine-borane in solution containing sodium laurate at room temperature. The water soluble laurate-stabilized rhodium(0) nanoclusters in average size of 5.2 +/- 2.7 nm could be isolated from the reaction solution and characterized by using UV-vis, TEM, XPS, XRD and FTIR spectroscopic methods. Catalytic activity of rhodium(0) nanoclusters was tested in the hydrolysis of ammonia-borane. They show exceptional catalytic activity and unprecedented catalytic lifetime in this reaction. They provide a TOF value of 200 mol H-2/mol Rh min and 80,000 turnovers in the hydrolysis of ammonia-borane in air at 25.0 +/- 0.1 degrees C.

Immobilization of dioxomolybdenum(VI) complex bearing salicylidene 2-picoloyl hydrazone on chloropropyl functionalized SBA-15: A highly active, selective and reusable catalyst in olefin epoxidation Bagherzadeh, Mojtaba; Zare, Maryam; Salemnoush, Taghi; Özkar, Saim; Akbayrak, Serdar (Elsevier BV, 2014-04-05) A novel organic-inorganic hybrid heterogeneous catalyst system was obtained from the reaction of the molybdenum(VI) complex of salicylidene 2-picoloyl hydrazone with mesoporous silica containing 3-chloropropyl groups prepared by a direct synthetic approach involving hydrolysis and co-condensation of tetraethylorthosilicate (TEOS) and 3-chloropropyltrimethoxysilane in the presence of the triblock copolymer P123 as template under acidic conditions. Characterization of the functionalized materials by X-ray dif...
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 ...
Intrazeolite cobalt(0) nanoclusters as low-cost and reusable catalyst for hydrogen generation from the hydrolysis of sodium borohydride Rakap, Murat; Özkar, Saim (Elsevier BV, 2009-09-07) Intrazeolite cobalt(0) nanoclusters were prepared by ion-exchange of Co2+ ions with the extraframework Na+ ions in the zeolite-Y followed by the reduction of Co2+ ions in the supercages of zeolite-Y with sodium borohydride at room temperature. The intrazeolite cobalt(0) nanoclusters were isolated as solid materials and characterized by ICP-OES, XRD, HRTEM, SEM, XPS, Raman spectroscopy and N-2 adsorption technique. The catalytic activities of intrazeolite cobalt(0) nanoclusters in the hydrolysis reaction of ...
PVP-stabilized nickel(0) nanoparticles as catalyst in hydrogen generation from the methanolysis of hydrazine borane or ammonia borane Ozhava, Derya; Kilicaslan, Nihan Z.; Özkar, Saim (Elsevier BV, 2015-01-01) Herein we report the results of a detailed study on the in-situ generation of poly(N-vinyl-2-pyrrolidone) (PVP) stabilized nickel(0) nanoparticles and their catalytic activity in methanolysis of hydrazine borane and ammonia borane. PVP-stabilized nickel(0) nanoparticles with an average particle size of 3.0 +/- 0.7 nm were in-situ generated from the reduction of nickel(II) 2-ethylhexanoate during the methanolysis of hydrazine borane in the presence of PVP at room temperature. Polymer stabilized nickel(0) nan...
In situ DRIFTS characterization of wet-impregnated and sol-gel Pd/TiO 2 for NO reduction with CH4 Karakaş, Gürkan; Ozkan, Umit S. (Elsevier BV, 2002-05-01) The adsorption/desorption behavior of 2%Pd/TiO2 catalysts synthesized by wet-impregnation and modified sol–gel techniques were examined in NO–CH4–O2 reaction using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The catalyst prepared by the modified sol–gel method showed significantly higher resistance toward oxygen while maintaining a 100% NO conversion. Under NO+CH4+O2 flow, the main adsorbed NO species was identified as the linearly adsorbed NO on metallic palladium (Pd0–NO)...
