5.1 Introduction
Carbon materials possess valuable properties for the design of
electrodes used in electroanalytical chemistry, because of their
relatively wide potential windows in aqueous media, low cost, and
relative chemical inertness in most electrolyte solutions. There
are several available microstructures of carbon materials, such as
diamond, amorphous powders,
