Reduced-Graphene-Oxide with Dispersed Au-Ir Nanoparticles as Active Support for Pt at low Loadding for Electrocatalytic Oxygen Electroreduction
Sylwia Zoladek, Magdalena Blicharska, Anna Jablonska +9
We report here on a novel and facile techniques for the synthesis nanocomposite based on stable bimetallic catalyst containing iridium and gold nanoparticles electrodeposited on ch…
Development of nanostructured-graphene-supported silver nanoparticles as catalysts for electroreduction of oxygen in alkaline electrolyte
Sylwia Zoladek, Magdalena Blicharska, Agnieszka Anna Krata +6
Here we develop a class off face centred cubic structure of metallic silver nanocrystals, to enable high ORR activity process. Silver nanoparticles deposited within different carbo…
Evaluation of reduced-graphene-oxide-supported gold nanoparticles as catalytic system for electroreduction of oxygen in alkaline electrolyte
Sylwia Zoladek, Iwona A. Rutkowska, Magdalena Blicharska +6
Chemically-reduced graphene-oxide-supported gold nanoparticles are considered here as catalytic materials for the reduction of oxygen in alkaline medium. Gold nanoparticles are pre…
Reduced-Graphene-Oxide with Traces of Iridium or Gold as Active Support for Pt Catalyst at Low Loading during Oxygen Electroreduction
P. J. Kulesza, B. Dembinska, S. Zoladek +4
Chemically-reduced graphene-oxide-supported gold or iridium nanoparticles are considered here as active carriers for dispersed platinum with an ultimate goal of producing improved…
Oxygen reduction reaction electrocatalysts based on FeSn0.5 species embedded in hierarchical CN-graphene based supports
Enrico Negro, Angeloclaudio Nale, Keti Vezzu' +9
This work reports the synthesis, the physicochemical characterization and the electrochemical studies of new electrocatalysts (ECs) for the oxygen reduction reaction (ORR) that: (i…
Towards 'Pt-free' Anion-Exchange Membrane Fuel Cells: Fe-Sn Carbon Nitride-Graphene 'Core-Shell' Electrocatalysts for the Oxygen Reduction Reaction
Enrico Negro, Antoine Bach Delpeuch, Keti Vezzu' +12
We report on the development of two new Pt-free electrocatalysts (ECs) for the oxygen reduction reaction (ORR) based on graphene nanoplatelets (GNPs). We designed the ECs with a co…
