rotating disc electrode

initialism: RDE
mentioned: rotating ring-disk electrode (RRDE)
https://doi.org/10.1351/goldbook.09124
A disc electrode that is embedded in the centre of a cylinder which rotates in solution around the longitudinal cylinder axis.
Notes:
  1. The limiting current is given by the Levich equation.
  2. The current is directly proportional to the electrode area and the electrode is uniformly accessible.
  3. A second annular working electrode may be positioned concentric with the disc to make a rotating ring-disc electrode (RRDE). This arrangement is largely used in mechanistic studies.
