An Electrochemical and Spectroscopic Characterization of Pencil Graphite Electrodes

“…30 The use of glassy carbon (GC) electrodes in electrochemical experiments has been widely reported in the literature because of their wide potential range, low porosity, and compatibility with a wide variety of electrolytes. [31][32][33][34] Prior to each electrochemical measurement, the GC electrode must be cleaned, usually by polishing with alumina slurry. The most commonly used procedure involves polishing the electrode with successive 1.0, 0.3 and 0.05 μm alumina slurries.…”
