Rotating Disk and Ring-Disk Electrodes in Investigations of Surface Phenomena at the Metal-Electrolyte Interface

Ring Electrodes

“…Matsuda (12) showed a method to compute current distributions for redox reactions on rings of any thickness. Similar work (13,14) can be found in the literature on ring-ring electrodes for rapid heterogeneous reactions where the inner ring is decoupled from the outer ring since the kinetics are not considered to be potential dependent.…”

“…A high Schmidt-number formulation of the convective diffusion equation appropriate for binary electrolytes and minor reacting components in a solution with an excess of supporting electrolyte, where migration effects can be safely ignored, has been used in most of the previous studies involving potential independent heterogeneous kinetics (10,(12)(13)(14). An integral equation has proven useful for computing analytic and numerical results.…”
