Figure Lengend Snippet: (a) Technical drawing of the spectroeletrochemical GIXAS cell including four M5 screws (1), the working electrode part (2), graphene foil with catalyst (3), alignment pins (4), ice cube gaskets (5, 9, 11, 14), the working electrode compartment (6), porous glass frits (7), PTFE frit holders (8), Nafion XL membrane (10), leak-free Ag/AgCl reference electrode (12), the counter electrode compartment (13), platinum counter electrode (15), the counter electrode current collector (16), four PEEK inserts (17), four M5 nuts (18), and two gold pins inserted into PEEK screws (19). (b) Side view of the GIXAS cell for better illustration of the beam entrance slit and fluorescence window.
Article Snippet: For the preparation of the electrodes, the AuCu aerogel catalyst was deposited by drop-casting onto 35 μm thick graphene sheets (Nanografi) using the following ink formulation.
Techniques: Membrane, Fluorescence
