Rhodium(0) nanoparticles supported on hydroxyapatite nanospheres and further stabilized by dihydrogen phosphate ion: A highly active catalyst in hydrogen generation from the methanolysis of ammonia borane
Ozhava, Derya; Özkar, Saim (Elsevier BV, 2015-09-07)
Rhodium(0) nanoparticles, supported on nanosized hydroxyapatite (Rh(0)/nanoHAP), were prepared by ion exchange of Rh+3 ions with Ca+2 ions of hydroxyapatite, followed by reduction of the resulting Rh+3/nanoHAP precatalyst during the catalytic methanolysis of ammonia borane (AB) in the presence of tetrabutylammonium dihydrogen phosphate (TBAP) at room temperature. Rh(0)/nanoHAP were characterized by a combination of advance analytical techniques including ICP-OES, XRD, TEM, EDX, XPS, ATR-IR and N-2 adsorptio...
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...
Rhodium(0) nanoparticles supported on nano oxide crystalline materials: preparation, characterization and catalytic use in hydrogen generation from the methanolysis of ammonia borane /
Özhava, Derya; Özkar, Saim; Department of Chemistry (2018)
Ammonia borane (AB) has been considered as a chemical hydrogen storage materials, because of its high hydrogen storage capacity (19.6 wt%), nontoxicity, and stability under ordinary conditions. Hydrogen stored in AB can be liberated by thermolysis or solvolysis. Hydrolysis and methanolysis are the two solvolysis reactions producing hydrogen gas from AB. Although the hydrolysis of AB has been investigated for years extensively, the methanolysis of AB has been considered as an alternative way of releasing hyd...
Rhodium(0) nanoparticles supported on nanotitania as highly active catalyst in hydrogen generation from the hydrolysis of ammonia borane
Akbayrak, Serdar; Gencturk, Serap; MORKAN, İzzet; Özkar, Saim (Royal Society of Chemistry (RSC), 2014-01-01)
Rhodium(0) nanoparticles supported on the surface of titanium dioxide (Rh(0)@TiO2) were in situ generated from the reduction of rhodium(III) ions impregnated on nanotitania during the hydrolysis of ammonia borane. They were isolated from the reaction solution by centrifugation and characterized by a combination of advanced analytical techniques. The results show that (i) highly dispersed rhodium(0) nanoparticles with sizes in the range 1.3-3.8 nm were formed on the surface of titanium dioxide, (ii) Rh(0)@Ti...
Rhodium(0) nanoparticles supported on hydroxyapatite: preparation, characterization and catalytic use in hydrogen generation from hydrolysis of hydrazine borane and ammonia borane
Çelik, Derya; Özkar, Saim; Department of Chemistry (2012)
This dissertation presents the preparation and characterization of rhodium(0) nanoparticles supported on hydroxyapatite, and investigation of their catalytic activity in hydrogen generation from the hydrolysis of hydrazine-borane and ammonia-borane. Rh+3 ions were impregnated on hydroxyapatite by ion-exchange; then rhodium(0) nanoparticles supported on hydroxyapatite were formed in-situ during the hydrolysis of hydrazine-borane at room temperature. The rhodium(0) nanoparticles supported on hydroxyapatite we...
