Evaluation of Reduced-Graphene-Oxide Aligned with WO3-Nanorods as Support for Pt Nanoparticles during Oxygen Electroreduction in Acid Medium
Iwona A. Rutkowska, Sylwia Zoladek, Anna Wadas +6
Hybrid supports composed of chemically-reduced graphene-oxide-aligned with tungsten oxide nanowires are considered here as active carriers for dispersed platinum with an ultimate g…
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…
Elucidation of role of graphene in catalytic designs for electroreduction of oxygen
Pawel J. Kulesza, Jerzy K. Zak, Iwona A. Rutkowska +6
Graphene is, in principle, a promising material for consideration as component (support, active site) of electrocatalytic materials, particularly with respect to reduction of oxyge…
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…
