Epinephrine Electro-oxidation Highlights Fast Electrochemistry at the Graphite Basal Surface

Macroscale and nanoscale measurements of epinephrine electro-oxidation at graphite electrodes, with different step edge densities, demonstrate unequivocally that the reaction occurs readily at the basal surface, and that step edges are not required for molecular electrocatalysis, in contrast to the current literature model.
