碳，特别是各种形式的石墨，是一种有吸引力的电极材料。两个特别感兴趣的领域是改性碳电极和碳纳米管电极。本文重点讨论了基于这些材料的电极的表面结构与电化学和化学反应性之间的关系。我们概述了最近在这一领域的工作，这使我们相信石墨碳电极的催化活性，电子转移和化学反应活性的大部分是在表面缺陷位点，特别是边缘平面状缺陷位点。我们也质疑碳纳米管修饰电极的特殊“催化”特性。
Carbon, and particularly graphite in its various forms, is an attractive electrode material. Two areas of particular interest are modified carbon electrodes and carbon nanotube electrodes. In this article we focus on the relationship between surface structure and electrochemical and chemical reactivity of electrodes based on these materials. We overview recent work in this area which has led us to believe that much of the catalytic activity, electron transfer and chemical reactivity of graphitic carbon electrodes is at surface defect sites, and in particular edge-plane-like defect sites. We also question the claimed special "catalytic'' properties of carbon nanotube modified electrodes.
