Electrochemistry of 2D nanomaterials

Abstract The electrochemical properties of 2D materials are discussed in this chapter with the aim to survey their behavior from a fundamental perspective. The relatively recent discovery of 2D materials, many of which are mostly surface-only substances, brings a new horizon to electrochemistry thanks to the nanoscale dimensions and unique electrochemical characteristics of these nanomaterials. Following a discussion of the relationship between 2D material electroactivity and structure, including the role of substrate and defects, we then consider ion conductivity through, and ion intercalation into, structures formed from 2D materials. Finally, we discuss in situ approaches involving electrochemical gating, photoelectrochemistry, spectroscopy, and strain engineering, which are employed to control and investigate the properties of 2D materials.
