Electrochemistry at Highly Oriented Pyrolytic Graphite HOPG Toward a New Perspective

Electrochemistry at Highly Oriented Pyrolytic Graphite (HOPG) Toward a New Perspective 

This chapter is concerned with electrochemistry at, and of, highly oriented pyrolytic graphite (HOPG), a material that has been studied intermittently for several decades, but which is of enduring interest particularly as a comparison to other types of carbon electrodes. Our aim is to give an overview of the field, with a particular focus on recent work that allows key models of the HOPG electrochemistry to be assessed. 

With the advent of new sp carbon materials, namely carbon nanotubes [11, 12] and then graphene [13-15], HOPG reemerged as an important reference material for electrochemical studies. Prominent work in the early 2000s drew strong comparisons between the electrochemistry of HOPG and multi-walled
