Ruthenium(0) nanoparticles were successfully prepared on the surface of ceria (Ru-0/CeO2) and used as catalysts on glassy carbon electrode (GCE) in oxygen evolution reaction (OER) from water electrolysis at room temperature. Ru-0/CeO2 on GCE exhibits high catalytic activity for OER in alkaline solution. It provides a low onset potential of 1.57 V vs. RHE and low overpotential of 420 mV vs. RHE to reach a current density of 10 mA cm(-2). Ru-0/CeO2 on GCE shows no change in the onset potential value even after 6.1 h electrochemical measurement in OER.

Ceria-supported ruthenium nanoparticles as highly active and long-lived catalysts in hydrogen generation from the hydrolysis of ammonia borane Akbayrak, Serdar; Tonbul, Yalcin; Özkar, Saim (2016-01-01) Ruthenium(0) nanoparticles supported on ceria (Ru-0/CeO2) were in situ generated from the reduction of ruthenium(III) ions impregnated on ceria during the hydrolysis of ammonia borane. Ru-0/CeO2 was isolated from the reaction solution by centrifugation and characterized by ICP-OES, BET, XRD, TEM, SEM-EDS and XPS techniques. All the results reveal that ruthenium(0) nanoparticles were successfully supported on ceria and the resulting Ru-0/CeO2 is a highly active, reusable and long-lived catalyst for hydrogen ...
Ceria supported rhodium nanoparticles: Superb catalytic activity in hydrogen generation from the hydrolysis of ammonia borane Akbayrak, Serdar; Tonbul, Yalcin; Özkar, Saim (2016-12-05) We investigated the effect of various oxide supports on the catalytic activity of rhodium nanoparticles in hydrogen generation from the hydrolysis of ammonia borane. Among the oxide supports (CeO2, SiO2, Al2O3, TiO2, ZrO2, HfO2) ceria provides the highest catalytic activity for the rhodium(0) nanoparticles in the hydrolysis of ammonia borane. Rhodium(0) nanoparticles supported on nanoceria (Rh-0/CeO2) were prepared by the impregnation of rhodium(III) ions on the surface of ceria followed by their reduction ...
Ceria supported manganese(0) nanoparticle catalysts for hydrogen generation from the hydrolysis of sodium borohydride DUMAN, SİBEL; Özkar, Saim (2018-08-09) Herein we report for the first time the preparation and catalytic use of the ceria supported manganese(0) nanoparticles in hydrogen generation from the hydrolysis of sodium borohydride. They are in situ formed from the reduction of manganese(II) ions on the surface of ceria nanopowders during the catalytic hydrolysis of sodium borohydride in aqueous solution at room temperature. Manganese(0) nanoparticles are isolated from the reaction solution by centrifugation and characterized by a combination of analyti...
Ceria Supported Nickel(0) Nanoparticles: A Highly Active and Low Cost Electrocatalyst for Hydrogen Evolution Reaction Demir Arabacı, Elif; Önal, Ahmet Muhtar; Özkar, Saim (2020-06-01) Herein, we report the development of a nickel-based catalyst obtained by reduction of Ni(2+)ions on the surface of ceria nanopowder using aqueous solution of NaBH4. The catalyst was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX) and X-ray photoelectron spectroscopy (XPS). Nickel(0) nanoparticles supported on nanoceria (Ni-0/CeO2) were employed as electrocatalyst on glassy carbon electrode (GCE) for H(2)evolution reaction. The modified...
Chromium substituted iron oxide nanowires as affordable electrocatalysts for oxygen evolution reaction Kocabas, Serra; Çetin, Asude; Önal, Ahmet Muhtar; Nalbant Esentürk, Emren (Springer Science and Business Media LLC, 2019-07-01) Earth-abundant metal oxides have become center of attention in the application of electrochemical energy conversion and storage. In this work, CrFeO3 was synthesized as a new catalyst for oxygen evolution reaction (OER). The structural and chemical properties of CrFeO3 were characterized by TEM, SEM, EDX, XRD, XPS, and BET analyses. The microscopy images reveal that CrFeO3 have wire-like morphology, which was formed by assembly of ca. 14nm nanocrystallites. Then, potential utility of the synthesized nanowir...
