摘要：

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.
