Morphology Changes Due to Oxidative Treatment of Glassy Carbon Electrodes and Its Applications
Abstract
Oxidative (anodic) treatment of glassy carbon(GC) in aqueous alkaline media was found to cause the formation of a unique mesa morphology. Injection of some species (perhaps OH(-)) below the surface with attendant volume change was suspected to be the cause for the peculiar morphological change. The present paper reports the mechanism of the mesa formation and its application to enhance the catalytic activity for electropolymerization of conducting polymers and the double-layer capacitance of the resulting polypyrrole/GC film. Keyword: Electrochemistry/catalysts.
