Figure 5.3 shows a schematic structure of the RDE. The disk electrode s planner surface is made to contact with the electrolyte solution. An electronic isolator made from isolating material such as Teflon is used to cover the remaining part of the disk with only the planner surface exposed. An electrical brush is used to make the electrical connection between the electrode shaft and the wire during the electrode rotating. When the electrode is rotating, the solution will run from the hulk to the surface, and then be flushed out along the direction parallel to the disk surface, as shown in Figure 5.3(B). Using these three coordinates r, x, and 0, shown in Figure 5.3 through a complicated mathematic operation, the solution flow rates near the electrode surface at x and r directions can be expressed as ...

A special form of a rotating electrode is the ring-disk electrode, a schematic diagram of which is shown in Fig. 63. The electrode is constructed from a centre disk which is conducting and is connected to its own voltage source and recorder. The ring, which is also conducting, is separated from the disk...
