Acid deprotonation driven by cation migration at biased graphene nanoflake electrodes.

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.
