Voltammetry of carbon nanotubes and graphenes: excitement, disappointment, and reality.

Voltammetry of carbon nanotubes and graphene underwent significant development in the first decade of the 21st century. The initial excitement concerning the performance of the new materials was replaced with increasing crises in the field caused by the use of impure materials. Here, I provide a personal view of these developments and some "reality checks" for the electrochemistry of these nanomaterials.
