应用扫描电化学显微镜研究电荷在液/液界面上的转移过程是目前电化学和电分析化学领域的研究热点之一。本文发展了一种制备金属纳米电极和SECM探头的方法.围绕着扫描电化学显微镜与纳米探头（金属、玻璃纳米管）的结合以及扫描电化学显微镜与极化的液/液界面的结合，本文研究了加速离子在可极化的液/液界面上的转移反应机理及其动力学，并对电子在液/液界面间的转移的Marcus理论做了较详细地探讨。

In this paper, a novel method to fabricate nano-metal electrodes and scanning electrochemical microscopy (SECM) tips has been developed, and fabricated electrodes were characterized by scanning electron microscopy (SEM), cyclic voltammetry and SECM. Based on the combination of nanoelectrodes (including metal and glass pipets) and SECM, and the droplet three-electrode system developed previously by our group, we have investigated the charge (electron and ion) transfer kinetics at the polarizable liquid/liquid interfaces. The experimental results demonstrate that the facilitated ion transfer (FIT) at liquid/liquid interface is potential dependent in a certain region, and the electron transfer (ET) kinetics can be explained by using the Marcus theory when the concentrations of the redox couple for each phase are appropriate.
