"Using scanning electrochemical cell microscopy, and co-located structural microscopy, the classical hexaamineruthenium (III/II) couple is measured on a graphene-metal electrode. Using model Hamiltonian and constant potential density functional theory, we can rationalize the fact that monolayer graphene shows faster kinetics than bilayer graphene and we are able to identify the electron transfer as dominantly adiabatic."
