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)...
Ceria supported ruthenium(0) nanoparticles: Highly efficient catalysts in oxygen evolution reaction Demir Arabacı, Elif; AKBAYRAK, SERDAR; Önal, Ahmet Muhtar; Özkar, Saim (2019-01-15) 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 temperatur...
Titania, zirconia and hafnia supported ruthenium(0) nanoparticles: Highly active hydrogen evolution catalysts Demir Arabacı, Elif; AKBAYRAK, SERDAR; Önal, Ahmet Muhtar; Özkar, Saim (Elsevier BV, 2018-12-01) Designing a cost-effective catalyst with high activity and stability for hydrogen evolution reaction (2H(+) + 2e(-) -> H-2) is a big challenge due to increasing demand for energy. Herein, we report the electrocatalytic act...
Nanoceria-Supported Ruthenium(0) Nanoparticles: Highly Active and Stable Catalysts for Hydrogen Evolution from Water Demir Arabacı, Elif; Akbayrak, Serdar; Önal, Ahmet Muhtar; AKBAYRAK, SERDAR (American Chemical Society (ACS), 2018-02-21) Ruthenium(0) nanoparticles supported on nanoceria (Ru-0/CeO2) were prepared by reduction of Ru3+ ions on the surface of ceria using aqueous solution of NaBH4. The Ru-0/CeO2 samples were characterized by advanced analytical...
