采用离子注入法制备了用于电分析的金属修饰金刚石电极。镍和铜离子被注入到不同的掺硼金刚石（BDD）薄膜中，每种离子的剂量为5 × 10（14）cm（-2）。用循环伏安法和流动注射分析法研究了碱性介质中葡萄糖氧化的电化学行为。这些电极在清洗过程中，即使经过强超声处理，也表现出高的催化活性和优异的电化学稳定性，背景电流较低。结果表明，金属离子注入法是一种很有前途的金刚石电极电化学性能控制方法。(C)2004 Elsevier B. V.保留所有权利。
Metal-modified diamond electrodes were fabricated by using ion implantation method for electroanalytical applications. Nickel and copper ion were implanted at a different film of boron-doped diamond (BDD) with a dose of 5 x 10(14) cm(-2) for each type of ion. The electrochemical behavior has been studied for glucose oxidation in alkaline media by using cyclic voltarnmetty and flow injection analysis. Those electrodes exhibited high catalytic activity and excellent electrochemical stability with low background current even after strong ultrasonication in the cleaning process. The results indicate that metal-implanted method could be a promising method for controlling the electrochemical properties of diamond electrodes. (C) 2004 Elsevier B.V. All rights reserved.
