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. 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. Highly oriented pyrolytic graphite (HOPG) is an important electrode material as a structural model of graphitic nanocarbons such as graphene and carbon nanotubes. Here, we apply scanning electrochemical microscopy (SECM) to demonstrate quantitatively that the electroactivity of the HOPG basal surface can be significantly lowered by the adsorption of adventitious organic

The graphite layers themselves may contain a number of defects and grain boundaries, even in the highly-oriented pyrolytic graphite material. The guest species may intercalate into different layers and transform graphite layers into different exfoliated stages. In the present communication we examine the system of highly oriented pyrolytic graphite (HOPG) in perchloric acid, as a model in order to elucidate the mechanism of electrochemical anion intercalation in graphite.

To minimize these influences, we examined the lithiation of highly oriented pyrolytic graphite (HOPG) disk electrodes, with the basal planes stacked normal to the disk thickness (0.5 mm). At first, the radially progressing lithiation of the HOPG disks was followed in situ by top-view optical monitoring of the golden LiC6 phase.

Although carbon electrodes have been used in electrochemistry for more than a century, there has been renewed recent interest in electron transfer at carbon surfaces due to the development of graphene and carbon nanotube (CNT) materials.
