Comparative chronoamperometry: spheres, discs, cylinders and bands

Abstract:

A parameter, the diffusion indicator α, introduced in this work, is derived from chronoamperometric current responses to obtain comparative information about the diffusion of an electrochemically active species from/to an electrode. The α values are used to investigate the diffusion to four electrodes with different geometries: microsphere, microdisc, microcylinder, and microband electrodes based on literature analytical and empirical equations for their chronoamperometric currents and the as...
