Double Layer Effects at Well Characterized Electrochemical Interfaces

本研究项目由分析和表面化学计划资助，涉及对自组装单层修饰的单晶贵金属电极和金电极的结构和性能进行实验和理论研究。福西特教授和他在加州大学戴维斯分校的学生将使用各种伏安方法和阻抗光谱来表征这些电极表面浸在各种非水溶剂中。在这些电极/溶液界面上，电位在双层上的分布以及溶剂对这一性质的影响将被确定。与这个实验推力相一致，理论工作将继续发展这些双层性质的解析表达式，可以很容易地被实验学家使用。本项目将对贵金属单晶电极和自组装单层修饰金电极在各种非水溶剂中的双层性能进行实验和理论研究。福西特教授和他在加州大学戴维斯分校的学生将在这项工作中使用各种电化学方法和阻抗谱，并将开发易于使用的描述电极/溶液界面双层的分析表达式。这项工作的结果将有助于理解溶剂对这些界面上电位分布的影响，这些知识与各种“绿色”技术有关。

This research project, supported by the Analytical and Surface Chemistry Program, involves an experimental and theoretical study of the structure and properties of single crystal noble metal electrodes and gold electrodes modified by self-assembled monolayers. Professor Fawcett and his students at the University of California at Davis will use a variety of voltammetric methods and impedance spectroscopy to characterize these electrode surfaces immersed in various nonaqueous solvents. The distribution of potential over the double layer at these electrode/solution interfaces and the effect of solvent on this property will be determined. In concert with this experimental thrust theoretical work will be pursued to develop analytical expressions for these double layer properties that can be easily used by experimentalists. The double layer properties of single crystal noble metal electrodes and gold electrodes modified by self-assembled monolayers in various nonaqueous solvents will be studied experimentally and theoretically in this project. Professor Fawcett and his students at the University of California at Davis will use a variety of electrochemical methods and impedance spectroscopy in this work and analytical expressions that describe the double layer at these electrode/solution interfaces that can be easily used will be developed. The results from this work will be contribute to understanding the effects of solvent on the distribution of potential at these interfaces and this knowledge has relevance to a variety of `green` technologies.
