Over the last decade, transition metal nanoparticles have attracted much attention owing to their unique properties, different to their bulk counterparts, which facilitate their application in different fields from materials science to engineering. Of particular interest, the use of transition metal nanoparticles in catalysis has brought transcendent efficiency in terms of activity, selectivity and lifetime to heterogeneous catalysis. In this account, we summarize the recent developments in the synthesis routes and the catalytic performance of transition metal nanoparticles tested in the hydrogen generation from the hydrolysis of ammonia-borane, which has been considered as one of the attractive materials for the efficient storage of hydrogen that is still one of the key issues in the "Hydrogen Economy".

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...
Metal nanoparticles in liquid phase catalysis; from recent advances to future goals
Zahmakiran, Mehmet; Özkar, Saim (2011-01-01)
Metal nanoparticles have attracted much attention over the last decade owing to their unique properties, different to their bulk counterparts, which pave the way for their application in different fields from materials science and engineering to biomedical applications. Of particular interest, the use of metal nanoparticles in catalysis has brought superior efficiency in terms of activity, selectivity and lifetime to heterogeneous catalysis. This article reviews the recent developments in the synthesis rout...
Phase transition of chemically synthesized FePt nanoparticles under high pressure
ŞİMŞEK, TELEM; Karci, Ozgur; ÖZCAN, ŞADAN (The Scientific and Technological Research Council of Turkey, 2018-01-01)
We present the results of a study related to phase transformation of chemically synthesized FePt nanoparticles under high pressure from face-centered cubic into face-centered tetragonal structure. As-synthesized nanoparticles are around 4.5 nm and show superparamagnetic behavior at 300 K. After annealing under 60 bar pressure of hydrogen at 400 degrees C for 2 h, nanoparticles exhibit strong ferromagnetic behavior with 5391 Oe coercivity. Results show that high-pressure annealing lowers the decomposition te...
Vanadium incorporated high surface area MCM-41 catalysts
Gucbilmez, Y; Doğu, Timur; Balci, S (Elsevier BV, 2005-02-28)
High surface area MCM-41 (1452 m(2)/g) and V-MCM-41 materials were synthesized by a direct hydrothermal synthesis method. Characteristic XRD patterns, SEM and AFM photographs indicated no significant change in the morphology of MCM-41 by incorporation of vanadium. XPS and EDS results proved that incorporation of vanadium into the MCM-41 structure was successfully achieved when vanadyl sulfate hydrate was used as the vanadium source. However, use of ammonium vanadate as the vanadium source was not equally su...
Oxygen Mobility in Pre-Reduced Nano- and Macro-Ceria with Co Loading: An AP-XPS, In-Situ DRIFTS and TPR Study
Sohn, Hyuntae; Çelik, Gökhan; Gunduz, Seval; Dogu, Doruk; Zhang, Shiran; Shan, Junjun; Tao, Franklin Feng; Ozkan, Umit S. (Springer Science and Business Media LLC, 2017-01-01)
The size effect of ceria nanoparticles on surface oxygen mobility and formation of surface oxygen vacancies in ethanol steam reforming was investigated. Higher concentration of Ce3+ surface sites of the ceria nano-particles (~4 nm, NP) was observed compared to the micro-particles (~120 nm, MP). Similarly, studies using ambient-pressure X-ray photoelectron spectroscopy (AP-XPS) exhibited higher intensity of O1s assigned to the hydroxyl group bonding to Ce3+ and significantly lower intensity for lattice oxyge...
