Immobilised Electrocatalysts: Nafion Particles Doped with Ruthenium (II) Tris(2,2'-bipyridyl)
Nafion particles novelly doped with ruthenium (II) tris(2,2'-bipyridyl) are synthesized by using the re-precipitation method. Characterization including SEM sizing and quantification of Ru(bpy)32+ in the Nafion particles via UV-Vis spectroscopy was conducted. The synthesized Ru-Nafion particles...

| description | Nafion particles novelly doped with ruthenium (II) tris(2,2'-bipyridyl) are synthesized by using the re-precipitation method. Characterization including SEM sizing and quantification of Ru(bpy)32+ in the Nafion particles via UV-Vis spectroscopy was conducted. The synthesized Ru-Nafion particles were investigated electrochemically at both ensemble and single particle levels. Voltammetry of the drop-cast Ru-Nafion particles evidences the successful incorporation of Ru(bpy)32+ into the Nafion particle but only a small fraction of the incorporated Ru(bpy)32+ was detected due at least in part to the formation of the likely agglomerated and irregular 'mat' associated with the dropcast technique. In contrast, nano-impact experiments provided a quantitative determination of the amount of Ru(bpy)32+ in single Ru-Nafion particles. Finally, oxidation of solution phase oxalate mediated by Ru(bpy)32+ within individual Nafion particles was observed, showing the electrocatalytic properties of the Ru-Nafion particles. |
