| Description |
Though graphitic carbons are commercially available for various electrochemical processes, their
performance is limited in terms of various electrochemical activities. Recent experiments on layered
carbon materials, such as graphene, demonstrated an augmented performance of these systems in all
electrochemical activities due to their unique electronic properties, enhanced surface area, structure and
chemical stabilities. Moreover, flexibility in controlling electronic, as well as electrochemical activities by
heteroatom doping brings further leverage in their practical use. Here, we study the electron transfer
kinetics of fluorinated graphene derivatives, known as fluorinated graphene oxide (FGO) and its reduced
form, RFGO. Enhanced electron transfer kinetics (heterogeneous electron transfer (HET)) is observed
from these fluorinated systems in comparison to their undoped systems such as graphene oxide (GO)
and reduced GO. A detailed study has been conducted using standard redox probes and biomolecules
revealing the enhanced electro-catalytic activities of FGO and RFGO, and electron transfer rates are
simulated theoretically. This study reveals that fluorine not only induces defects in graphitic lattice
leading to an enhanced HET process but also can modify the electronic structure of graphene surface
