Carbon is a conventional electrode material that has generally been used for electroanalysis. It has been extensively used in electroanalytical detection because of its low background current, chemical inertness, comparatively extensive potential window, inexpensiveness and electrocatalytic activity for various analytes. 1 Numerous types of carbon-based electrodes have been exploited for electrochemical applications including energy conversion and storage, photovoltaics, catalysis, electrochemical sensors, biosensors, etc. 2–5 Glassy carbon electrodes, carbon paste electrodes, pencil graphite electrodes,
