Graphene nanoflakes (GNF) of diameter ca. 30 nm and edge-terminated with carboxylic acid (COOH) or amide functionalities were characterised electrochemically after drop-coating onto a boron-doped diamond (BDD) electrode. In the presence of the outer-sphere redox probe ferrocenemethanol there was no discernible difference in electrochemical response between(More)
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.
