Zeolite confined copper(0) nanoclusters as cost-effective and reusable catalyst in hydrogen generation from the hydrolysis of ammonia-borane
Zahmakiran, Mehmet; Durap, Feyyaz; Özkar, Saim (2010-01-01)
Herein we report the development of a cost-effective nanocluster catalyst for the hydrolytic dehydrogenation of ammonia-borane which is considered to be one among the new hydrogen storage materials. Zeolite confined copper(0) nanoclusters were prepared by the ion-exchange of Cu2+ ions with the extra framework Na+ ions in zeolite-Y followed by reduction of the Cu2+ ions within the cavities of zeolite with sodium borohydride in aqueous solution and characterized by HR-TEM, XRD, XPS, SEM, EDX, ICP-OES, Raman s...
ZEOLATES - A COORDINATION CHEMISTRY VIEW OF METAL-LIGAND BONDING IN ZEOLITE GUEST HOST INCLUSION-COMPOUNDS
OZIN, GA; Özkar, Saim (American Chemical Society (ACS), 1992-05-01)
Various guests have been investigated in zeolite hosts in our laboratory over the past five years. From analysis of in situ spectroscopic observations (FT-IR, UV-vis, Mossbauer, DOR-MAS NMR) of the reaction sequences and structural features of precursors and products (EXAFS, Rietveld refinement of powder XRD data), the molecule size cavities and channels of zeolites respectively are viewed as providing macrospheroidal and macrocylindrical, multisite multidentate coordination environments toward encapsulated...
Zeolite framework stabilized nickel(0) nanoparticles: Active and long-lived catalyst for hydrogen generation from the hydrolysis of ammonia-borane and sodium borohydride
Zahmakiran, Mehmet; Ayvali, Tugce; Akbayrak, Serdar; Caliskan, Salim; Celik, Derya; Özkar, Saim (Elsevier BV, 2011-07-19)
Among the hydrogen storage materials, ammonia-borane and sodium borohydride appear to be promising candidates as they can release hydrogen on hydrolysis in aqueous solution under mild conditions. Here, we report the development of a cost-effective and highly active nickel(0) nanoparticles catalyst for the hydrolysis of ammonia-borane and sodium borohydride. Nickel(0) nanoparticles confined in zeolite framework were prepared by using our previously established procedure and characterized by ICP-OES, XRD, TEM...
Zeolite confined rhodium(0) nanoclusters as highly active, reusable, and long-lived catalyst in the methanolysis of ammonia-borane
Caliskan, Salim; Zahmakiran, Mehmet; Özkar, Saim (Elsevier BV, 2010-01-12)
Addressed herein is the preparation, characterization and the catalytic use of zeolite confined rhodium(0) nanoclusters in the methanolysis of ammonia-borane. Rhodium(0) nanoclusters; could be generated in zeolite-Y by a two-step procedure: (i) incorporation of rhodium(Ill) cations into the zeolite-Y by ion-exchange and (ii) reduction of rhodium(Ill) ions within the zeolite cages by sodium borohydride in aqueous solution, followed by filtration and dehydration by heating to 550 degrees C under 10(-4) Torr. ...
Zeolites as Host Materials: Synthesis, Post-Synthesis Treatments and Antimicrobial Properties of Zeolites
İşler Binay, Melda; Akata Kurç, Burcu; Kart, Didem; Department of Micro and Nanotechnology (2021-12-21)
The development of more efficient and eco-friendly antimicrobial agents with a broader spectrum plays a significant role in culminating prolonged treatment and higher global health. However, the worldwide rise multidrug-resistant bacteria has made traditional approaches to controlling infectious diseases problematic. As a result, developing new classes of antimicrobial medicines capable of treating resistant bacteria is critical. It is stated that using a host as a matrix in applying some antimicrobial agen...
