Application of Carbon-Based Thin-Film Electrode Materials in Electroanalytical Chemistry

由于具有一系列的优点,碳材料被广泛应用于电分析化学。新型碳电极材料的开发及其性质研究对电分析化学的发展起着重要的推动作用。最近报道了一些制备新型碳薄膜电极材料的方法,因为制备方法不同,这些碳薄膜材料的电化学性质如电位窗、稳定性、导电性也存在显著的差异。目前电位窗宽、背景电流低、稳定性高、表面不易被电极产物钝化的碳薄膜电极材料的研究非常活跃。本文综述了采用不同方法制备的一些碳薄膜电极材料如硼掺杂的金刚石薄膜、无定形碳和纳米晶体碳薄膜材料等在电分析化学中应用。

Carbon materials have been widely used in electroanalytical 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.
