Graphene-Supported Silver-Iron Carbon Nitride Derived from Thermal Decomposition of Silver Hexacyanoferrate as Effective Electrocatalyst for the Oxygen Reduction Reaction in Alkaline Media
Beata Dembinska, Kamila Brzozowska, Adam Szwed +4
Silver-iron carbon nitride has been obtained by pyrolysis (under inert atmosphere) of silver hexacyanoferrate(II), precipitated on graphene nanoplatelets, and examined as electroca…
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…
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…
