Application of carbon-based thin-film electrode materials in electroanalytical chemistry

Carbon materials have been widely used in eleetroanalytical chemistry because they have a number of advantageous properties. The development of new carbon-based electrode materials with improved properties promotes the advance of electroanalytical chemistry significantly. Recently, several methods have been reported for the preparation of new carbon-based thin films. These films differ significantly as regards such electrochemical properties as potential window, stability, and conductivity as a result of the different deposition procedures. Great interesting is attracted on carbon-based thin-film electrode materials which have wide potential window, low background current, high stability, and less easily passivated by the products of redox reactions. The application of several kinds of carbon-based thin-film electrode materials such as boron-doped diamond film, amorphous carbon, and nanocrystalline carbon thin-film in electroanalytical chemistry is reviewed.
