中文摘要： 纳米金刚石粉末由尺寸为纳米级的金刚石微粒组成，除具有金刚石的一般特性外，还具有纳米材料的众多特性，表面有着大量的结构缺陷和表面官能团，这使得其导电性有大幅度提高。而且表面吸附有大量的含氧、氮官能团，较大颗粒金刚石相比，具有较高的化学活性，可以通过化学处理和修饰对表面加以调节，将其用于电化学分析检测领域，可能成为新型的电极材料。 本项目拟采用纳米金刚石粉末电极，考察它在特定有机物溶液中的电化学性质，研究纳米金刚石粉末电极对于不同有机物的检测限。通过对于纳米金刚石粉末电极进行化学处理和表面修饰，使表面发生变化，考察其对于有机物检测的影响。

英文摘要： Nanodiamond(ND) powder which are made up of the nanosacle diamond particles, not only have the properties of diamond, but aslo possess the features of a nanoscale material, such as ultrafine particle size and large numbers of surface defects as well as giant specific surface area. Due to these properties, the conductivity of ND has been improved. Compared with large particle diamond, ND's surface adsorption has a large amount of oxygen, nitrogen functional groups, which provide higher chemical activity to ND. Therefore, ND's surface state could be modified by chemical treatment easily. In short,because of these unique properties, ND is expected to use as an electrode material in electrochemical fields. This project intends to study the electrochemical properties of the ND powder electrode in the chosen organic compounds solution. The detection limit for different organic compounds would be also investigated. Moreover, the effect of modifying surface state for detection limit would be studied.
