利用化学气相沉积法在钨衬底上生长碳电极 ,用扫描电镜对其表面形貌进行观测 ,发现表面碳微粒形状规则 ,微粒尺寸约为 2～ 3μm ,但是排列无序。用此电极作为研究电极 ,在 0 .1MKCl溶液中做循环伏安法扫描 ,结果表明 ,该电极电位窗口高达 2 .4 5V ,其中窗口正电位达 2 .2V ,它与传统的碳电极(石墨 ,玻璃碳 )和衬底钨电极都有很大的不同。实验还发现该电极具有很好的电化学稳定性和可重复性 ,在电化学测量时无需预处理等优点。因此 ,它可作为一种新型优质的分析电极 Carbon electrodes were grown on tungsten substrates by chemical vapor deposition. The surface morphology of the carbon electrodes was observed by scanning electron microscopy. The surface morphology of carbon particles was found to be about 2 ~ 3μm in size, but disordered. Using this electrode as a research electrode, cyclic voltammetry was performed in a 0.1 M KCl solution. The results showed that the potential window of this electrode was as high as 2.4 V, the positive potential of the window reached 2.2 V, which was in agreement with the traditional carbon electrode , Glassy carbon) and the substrate tungsten electrode are very different. The experiment also found that the electrode has good electrochemical stability and repeatability, electrochemical measurement without pretreatment and so on. Therefore, it can be used as a new type of high-quality analytical electrode
