Abstract

Recently, tremendous research efforts have been performed to study nanoelectrochemistry. However, most of researchers are not trying to elucidate electron transfer kinetics at nanoelectrodes but just focusing on electrochemical characterization of nanomaterials.

There are several papers which show that electrochemical behavior of nanoelectrodes (<100 nm) is quite different from that of bulk electrodes. To the best of my knowledge, there are some anomalies and controversies in terms of theory as well as experimental observation because it is difficult to reproducibly fabricate nanoelectrodes.

I will present nanoscale electrochemical behavior at graphite and graphene using scanning electrochemical cell microscopy (SECCM). From the SECCM movies, it is found that there are many nanostructures such as step-edge and basal planes showing different electrochemical behavior.
