Acid deprotonation driven by cation migration at biased graphene nanoflake electrodes

Abstract:
In situ IR spectroscopy is used to monitor electrolyte composition and acid protonation state at the interface of graphene nanoflake electrodes. Deprotonation of both electrode-immobilised and solution acids is driven by a local increase in cation activity at the electrode surface on application of a negative electrode potential.
