Studies of well-defined electrode surfaces have generally used single crystals of noble metals, however there are many open questions relating to the electrochemical properties of graphite and its 2-dimensional analogue, graphene. Graphite can be obtained in high purity form, either synthetically or as a natural material, and can readily be “cleaved” to regenerate smooth, nominally “clean” surfaces. In fact, the emergence of graphene has generated considerable debate about the intrinsic cleanliness of graphite surfaces [1,2], which relates to the parallel debate about the electroactivity of graphitic/graphene materials [3,4]. We will present data following on from our recent work on the electroactivity of mechanically-exfoliated graphene samples [5,6], and show how a facile strategy based on the adsorption of graphene at the organic/water interface can be used to functionalise this material . Finally, new phenomena, such as the recently observed proton conductivity of 2D materials will be briefly discussed .
