Abstract

The basal plane pyrolytic graphite (BPPG) electrode is widely used as a "standard" electrode for studies of electrochemical activity of graphite, graphene and carbon nanotubes. We compared here different methods for preparation of the surface of BPPG using statistical analysis of the data. We showed that including/omitting of polishing step or including/omitting of acetone washing step in the preparation procedure exhibits statistically significant difference. However, using acetone of different purities does not lead into statistically significant results. In addition, all methods with BPPG provided RSD < 10% and did not produce any outlying results.
