an ionic liquid (IL), was mixed together with the 3-D graphene, forming a porous nano-
composite gel. This was cast onto a glassy carbon electrode (GCE), followed by a layer of
Naon to prevent leaching of the hydrophobic IL and to potentially prevent interfering
species like ascorbic acid and nitrite. The Naon/3-D graphene–IL/GCE behaved like a
planar electrode at low scan rates but a thin-layer cell at high scan rates due to its porosity.
NO could be electrocatalytically oxidized on the Naon/3-D graphene–IL/GCE based on
the following electrochemical–chemical reactions:
