The article presents author's views on the use of carbon nanowalls as material for electrochemical transducers. According to him the amorphous carbon is not a suitable electrode for electrochemical studies. He states that the classic Randle Sevcik equation used to estimate the electroactive surface area is not valid for the system. He states that reasons including surface roughness, nonuniform current distribution, and nonuniform material composition are responsible for a constant phase element.
