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翻转现象做了较详细的探讨.
The application of scanning electrochemical microscope to study the charge transfer process at the liquid / liquid interface is one of the hot topics in the field of electrochemical and electroanalytical chemistry.In this paper, a method for preparing metal nano-electrode and SECM probe has been developed. The combination of chemical microscope with nano-probes (metal, glass nanotubes) and the combination of scanning electrochemical microscopy with polarized liquid / liquid interface, this paper studies the transfer reaction mechanism of accelerated ions on polarizable liquid / liquid interface and Its kinetics, and the phenomenon of Marcus overturning caused by electron transfer between the liquid / liquid interface are discussed in more detail.
