Developments on the modification of graphite electrodes with nanoparticles

The surface structure of common graphite electrodes are suitable for electrochemical detection of various analytes due to their favorable properties such as good conductivity and resistance toenvironmental. The material of the graphite electrodes (GEs) is low in cost, easily maintained,displays strong adsorption properties, low background current, and good electrocatalytic properties toward some electroactive molecules, and displays a wide potential window .Themodification of GPEs, using a suitable electrocatalyst such as nanomaterials, is crucial to the fabrication of sensitive electrochemical sensors. Modifying graphite electrodes with nanoparticles has attracted lots of attention due to their unique characteristics. In this article we investigated on the application of modified graphite electrodes with nanomaterials.
