Activation and deactivation of glassy carbon electrodes
TL;DR: In this paper, a procedure for treating glassy carbon to create an active electrode was described, and a level of activity comparable to that of active Pt has been attained, determined by the heterogeneous electron transfer rate (0.14±0.01 cm/s) of ferri-/ferro-cyanide.
